Abstract:
The existence of superconductivity in graphite has been under discussion since the 1960s when it was found in intercalated graphitic compounds, such as C8K, C8Rb and C8Cs. However, it was only about 40 years ago when the existence of superconductivity in pure graphite came up. In this work we directly investigate the interfaces highly oriented pyrolytic graphite (HOPG) has in its inner structure, since they play a major role in the electronic properties. The results obtained after studying the electrical transport provide clear evidence on granular superconductivity localized at the interfaces of graphite samples. Zero resistance states, strong current dependence and magnetic field effect on the superconducting phase support this statement. Additionally, an abrupt reduction in the measured voltage at temperatures from 3 to 175 K has been observed. However, the upper value of this transition temperature seems to not have been reached yet. A possible method to enhance it is to increase the carrier density of graphite samples. In order to preserve to quasi-two-dimensional structure of highly oriented pyrolytic graphite, chemical doping has been dismissed in the frame of this work. We used an external electric field to move the Fermi level and, hence, try to trigger superconductivity in multi layer graphene samples. A drop on the resistance at around 17 K has been measured for a large enough electric field applied perpendicular to the graphene planes. This transition is strongly affected by magnetic field and only appeared at low temperatures. As a result of the studies included in this work, it appears clear that graphite has a superconducting phase located at certain interfaces with a very high transition temperature.

Abstract:
Systematic Raman scattering experiments were performed to compare the phonon properties in series of GICs BaC6, SrC6, YbC6 and CaC6. The key difference induced by changing the ions in this order is a reduction in the separation of the graphene layers, which is concurrent with an increase in the superconducting transition temperature Tc from < 80 mK to 11.5 K. It was possible to correlate the increase in Tc with a softening of an out-of-plane carbon related phonon, which was explained in terms of increased charge in the carbon-related electronic band. This provides evidence that the carbon-related phonons and electronic-bands are crucial to the superconductivity in these compounds. An in-plane carbon phonon was also measured, which was shown not to follow the Born-Oppenheimer approximation. Recent theoretical attempts to explain these effects cannot fully account for the observed electron-phonon scattering rate. Neutron scattering was also used to measure the high energy carbon-related phonons in CaC6. Due to the highly textured nature of the samples, special analytical techniques were developed to allow for the comparison between experiment and density functional theory (DFT). Overall, a good level of agreement between experiment and theory is found, which is significant in light of several other measurements of phonon related properties of CaC6, which disagree with the theoretical predictions. YbC6 was studied as a function of pressure to investigate the changes induced by reducing the layer separation. Tc initially increases consistent with the idea that moving the graphene layers closer increases Tc, however, at higher pressures Tc decreases disappearing at 7 GPa. These effects are discussed in light of a possible valence transition in YbC6.

Abstract:
This thesis concerns the discovery of superconductivity in the intercalated graphite compounds C6Yb and C6Ca. A novel technique for synthesis of these intercalates has been developed, and is presented in detail. These two materials are shown to superconduct at 6.5K and 11.5K respectively. The superconductivity is demonstrated by measurements of the magnetisation and resistivity. Initial measurements of the superconducting transition of these materials as a function of pressure shows an increase in the transition with increasing pressure.

Abstract:
Measuring with high precision the electrical resistance of highly ordered natural graphite samples from a Brazil mine, we have identified a transition at ∼350 K with ∼40 K transition width. The steplike change in temperature of the resistance, its magnetic irreversibility and time dependence after a field change, consistent with trapped flux and flux creep, and the partial magnetic flux expulsion obtained by magnetization measurements, suggest the existence of granular superconductivity below 350 K. The zero-field virgin state can only be reached again after zero field cooling the sample from above the transition. Paradoxically, the extraordinarily high transition temperature we found for this and several other graphite samples is the reason why this transition remained undetected so far. The existence of well ordered rhombohedral graphite phase in all measured samples has been proved by x-rays diffraction measurements, suggesting its interfaces with the Bernal phase as a possible origin for the high-temperature superconductivity, as theoretical studies predicted. The localization of the granular superconductivity at these two dimensional interfaces prevents the observation of a zero resistance state or of a full Meissner state.

Resumo: Neste trabalho serão apresentados os principais resultados obtidos peloautor no decorrer de seu doutorado. Os sistemas estudados eram compostos por grafite, grafeno, antimônio e interfaces de grafite/silício. Uma das partes do trabalho consistiu no estudo de efeitos de desordem estrutural sobre oscilações quânticas em grafite. O estudo revelou que a mosaicidade da grafite estudada, largamente utilizada para se determinar a qualidade de amostras de grafite pirolítico altamente orientado (HOPG), não apresenta correlação com a amplitude das oscilações quânticas no material. Ao invés disso, os experimentos mostraram uma clara correlação entre a rugosidade superficial, a mobilidade eletrônica média e a amplitude do efeito de Haas van Alphen no material. Os resultados indicam que deformações da superfície da grafite afetam fortemente a mobilidade eletrônica do material (reduzindo a amplitude de oscilações quânticas) sem reduzir sua anisotropia. No trabalho, também é discutida a possibilidade de que as oscilações quânticas em grafite estejam relacionadas com a existência de interfaces bem definidas na estrutura interna do material. Também foram estudadas propriedades de transporte elétrico interplanar em grafite no limite ultraquântico. Medidas de magnetorresistência interplanar para campos magnéticos de até 60 T acusaram a ocorrência de uma região de magnetorresistência positiva seguida de magnetorresistência negativa (MRN) para campos magnéticos suficientemente altos. O efeito persistia até temperatura ambiente. Ele é explicado considerando-se o tunelamento de férmions de Dirac entre níveis fundamentais de Landau de planos de grafeno adjacentes dentro da grafite. A região de MRN é mais pronunciada em grafites com menor mosaicidade, o que sugere que o alargamento de níveis de Landau seja responsável pela magnetorresistência positiva observada nas medidas ao longo do eixo c da grafite. Além disso, experimentos de magnetorresistência interplanar com campos magnéticos orientados paralelamente à direção dos planos da grafite apresentaram indícios de que o material se torna mais tridimensional com a redução da temperatura. Os resultados sugerem que a integral de overlap interplanar em grafite possui valor ?1 < 7 meV. Esse valor é muito inferior àqueles reportados na literatura considerando-se o modelo mais bem aceito para grafite, segundo o qual ?1 ? 380 meV. Nesta tese também são apresentados resultados inéditos obtidos pelo autor relacionados a efeito Hall quântico em grafeno crescido epitaxial mente sobre substratos de carbeto de silício, efeitos de desordem estrutural sobre as propriedades de transporte elétrico basal da grafite, supercondutividade em heteroestruturas de grafite e silício e supercondutividade em compósitos de antimônio-ouro
Abstract: In this thesis, experimental results obtained by the author during his PhD will be presented. The work consisted on the study of electrical and magnetic properties of Dirac semimetals and related heterostructures. Namely: graphite, graphene, graphite/silicon interfaces and antimony. Part of the work about graphite consisted on the study of the effects of structural disorder on the quantum oscillations in the material. Experimental results in the literature widely regard the mosaic spread in graphite as a good disorder parameter. However, in the present work, we report that the mosaicity of graphite samples does not correlate with their quantum oscillations¿ amplitude. Experiments have revealed a clear relation of surface roughness to the electronic mobility and the amplitude of the deHaas van Alphen effect in the material. The possibility that quantum oscillations in graphite are affected by the presence of sharp interfaces within its stacking structure is also discussed. We have also studied out-of-plane magnetoresistance properties in ultraquantum graphite. Experiments performed at magnetic fields B//c up to 60 T have shown the occurrence of positive c-axis magnetoresistance followed by a region of negative magnetoresistance (NMR). The NMR persists up to room temperature and has been explained in terms of the tunneling of electrons between zero-energy Landau levels of adjacent graphitic layers. The NMR is more evident in samples with low mosaicity, suggesting the positive c-axis magnetoresistance is induced by means of broadening of LL¿s by disorder. In addition, c-axis magnetoresistance measurements with magnetic fields perpendicular to c-axis (B?c) suggest that our samples undergo a 2D to 3D transition with the reduction of temperature. Based on our results, we estimate a value for the interplane hopping energy parameter ?1 < 7 meV. This value is at odds with the most accepted model for graphite, for which ?1 ? 380 meV. In this thesis, we also present unpublished results on the occurrence of quantum Hall effect in graphene grown epitaxially in silicon carbide substrates, on the effects of structural disorder in the basal electric properties of graphite

Resumo: Evidências experimentais e teóricas recentes de que a supercondutividade nas várias formas alotrópicas do carbono pode ocorrer em temperaturas próximas ou até acima da temperatura ambiente, desencadearam um grande interesse científico. Resultados do presente trabalho demonstraram a ocorrência de supercondutividade em compósitos de carbono vítreo-enxofre (CV-S) a T = 3 K. Nossas medidas revelaram que a supercondutividade ocorre em uma pequena fração da amostra, e que a grafitização do carbono amorfo parece ser uma condição necessária para disparar a supercondutividade. Apresentamos também evidências de supercondutividade à temperatura ambiente em sanduíches de grafite/Si, e demonstramos que a supercondutividade está associada à interface grafite/silício. O comportamento encontrado é semelhante ao conhecido para estruturas supercondutoras de baixadimensionalidade. Em particular, observamos oscilações do tipo Josephson em curvas características de corrente-tensão (I-V), bem como sua supressão pela aplicação de campo magnético. Além disso, o campo magnético perpendicular transforma as curvas características I-V do tipo supercondutor para tipo isolante, assemelhando-se à transição supercondutor-isolante induzida por campo magnético em redes de junções Josephson. Todos estes resultados indicam que a interface grafite/silício pode ser um material promissor para o desenvolvimento de dispositivos microeletrônicos sem dissipação à temperatura ambiente
Abstract: Recent both experimental and theoretical evidence that superconductivity in various allotropic forms of carbon can occur at temperatures near or even above room temperature, triggered a broad scientific interest. Results of the present work demonstrated the occurrence of superconductivity in carbon glassy-sulfur composites (CV-S) at T = 3 K. Our measurements revealed that the superconductivity occurs in a small fraction of the sample, and that the graphitization of the amorphous carbon seems to be a necessary condition to trigger the superconductivity. We also present evidence for the room temperature superconductivity in graphite/Si sandwiches and demonstrate that the superconductivity is associated with the graphite/silicon interface. The found behavior is similar to that known for low-dimensional superconducting structures. In particular, we have observed Josephson-type oscillations in current-voltage (I-V) characteristics as well as their suppression by applied magnetic field. Moreover, the perpendicular magnetic field transforms the superconducting-like to insulating-like I-V characteristics resembling the magnetic-field-driven superconductor-insulator transition in Josephsonjunction-arrays. All these results indicate that graphite-silicon interface can be a promising material for the development of microelectronic devices without dissipation at room temperature

Medidas de magneto-transporte realizadas em amostras de HOPG com eletrodos supercondutores de In ou In-Pb revelaram a ocorrência de efeito de proximidade em uma escala muito maior que o comprimento de coerência dos eletrodos supercondutores, o que indica que a grafite pode ser considerada um supercondutor com flutuações de fase. Além disso, nossos estudos revelaram uma supressão do efeito de proximidade para campos magnéticos da ordem de 1 kOe aplicado perpendicularmente aos planos de grafite.

Abstract: In order to verify the existence of superconducting correlations in graphite, in this work we studied the possibility of the so-called giant proximity effect in highly oriented pyrolytic graphite (HOPG) samples. Magnetoresistance measurements performed on various thoroughly characterized HOPG samples with attached superconducting In or Pb-In electrodes revealed the occurrence of proximity effect on a scale much bigger than a coherence length of superconducting electrodes, indicating that graphite can be considered as a phase-fluctuating superconductor, indeed. Besides, our studies revealed a suppression of the proximity effect in magnetic field H ~ 1 kOe applied perpendicularly to graphene planes. Additionally, we performed comparative studies of the proximity effect in semimetallic bismuth. We discuss the obtained results in terms of available theoretical models.

Abstract:
Since the first isolation of graphene in 2004 interest in superconductivity and the superconducting proximity effect in monolayer or few-layer crystals has grown rapidly. This thesis describes studies of both the proximity effect in single and fewlayer graphene flakes, as well as the superconducting transition in few unit cell chalcogenide flakes. Optical and atomic force microscopy and Raman spectroscopy have been used to characterise the quality and number of molecular layers present in these flakes. Graphene structures with superconducting Al electrodes have been realised by micromechanical cleavage techniques on Si/SiO2 substrates. Devices show good normal state transport characteristics, efficient back-gating of the longitudinal resistivity, and low contact resistances. Several trials have been made to investigate proximity-induced critical currents in devices with junction lengths in the range 250-750 nm. Unfortunately, no sign of proximity supercurrents was observed in any of these devices. Nevertheless the same devices have been used to carefully characterise proximity doping, (due to the deposited electrode), and weak localisation/anti-localisation contributions to the conductivity in them. In addition this work has been extended to investigations of the superconducting transition in few unit-cell dichalcogenide flakes. Four-terminal devices have been realised by micromechanical cleavage from a 2H-NbSe2 single crystal onto Si/SiO2 substrates followed by the deposition of Cr/Au contacts. While very thin NbSe2 flakes do not appear to conduct, slightly thicker flakes are superconducting with an onset ܶ௖ that is only slightly depressed from the bulk value (7.2K). The resistance typically shows a small, sharp, high temperature transition followed by one or more broader transitions, which end in a wide tail to zero resistance at low temperatures. These multiple transitions appear to be related to disorder in the layer stacking rather than lateral inhomogeneity. The behaviour of several flakes has been characterised as a function of temperature, applied field and back-gate voltage. The resistance and transition temperatures are found to depend weakly on the gate voltage. Results have been analysed in terms of available theories for these phenomena.

Abstract:
Theoretical and experimental work on superconductivity has won a number of Nobel prizes in Physics, beginning with the prize to Kamerlingh Onnes in 1913 that included the initial discovery of superconductivity in mercury. Superconductivity has since been at the forefront of research in condensed matter physics. Furthermore, since the first isolation of graphene by Geim and Novoselov in 2004, there has been growing interest in other monolayer and few-layer crystals. Like graphene, other materials can be exfoliated due to the weak van der Waals interactions between layers, primarily the transition metal dichalcogenides (TMDs). Atomically flat and chemically stable thin two dimensional (2D) layers of TMDs have opened up new opportunities for discovering exciting new physics and ultimately developing thin flexible devices. Defect-free exfoliated TMDs are regarded to be ideal materials for use as channels for field effect transistors (FET), which have been shown to possess remarkable electronic properties. Recent advances in field effect-based TMD devices have been achieved using ionic liquid gating and the formation of electrical double layers. Using the techniques previously developed for isolating graphene, few-layer crystals of 1T- and 2H-TaS2 have been obtained in this project to be used as channel materials for FET and ionic field effect transistor (iFET) devices that incorporate DEME-TFSI ionic liquids as a top gate to control the carrier density. In the first experimental chapter (chapter 5) iFETs using a 1 μm thin film of a highly boron-doped diamond (BDD) as the channel material are introduced and the influence of top gating on the transition temperature using a DEME-TFSI ionic liquid is studied. An enhancement in the Tc of the BDD sample under positive top gate potentials is shown as a result of electron doping at the grain boundaries leading to stronger coupling between the grains. The following chapter (Chapter 6) describes low temperature measurements of graphene FET (GFET) devices. These devices were fabricated to enable a reliable and effective calibration for the DEME-TFSI top gate specific capacitance against the known back gate capacitance. This represents a valuable reference for ionic liquid gating studies of TMD materials. The last experimental chapter describes the electrical properties of few-layer 1T-TaS2 (initial section) and 2H-TaS2 (final section) samples used as channels in FET devices. Charge density wave (CDW) transitions in 1T- and 2H-TaS2 are investigated and gating measurements using ionic liquids on these samples are described and summarised. Although no gate influence was seen on the CDW in 2H-TaS2 , a suppression of the CDW transition in cooling cycles of a 1T-TaS2-based FET sample was observed. This suppression demonstrates that accumulation of additional charge carriers in the sample drives it into a metallic state. In a ∼15 nm 2H-TaS2 FET device, strong enhancement of the superconducting critical temperature from 0.8 to 4.7 K is observed with DEME-TFSI top gating. The influence of an additional back gate potential on the device enhances the transition temperature still further up to 5 K. This indicates a co-operative effect between the top and back gates of the sample. It was also demonstrated that 2H-TaS2 crystals are susceptible to intercalation by DEME+ cations in the ionic liquid; a clear enhancement of Tc was observed after simply placing a drop of ionic liquid on a 2H-TaS2 flake without application of a top gate bias. This research project has studied superconductivity in 2D materials and illustrates the capability of ionic liquid gating as a versatile tool to modify the carrier concentration and enhance the critical temperature of a wide range of different materials.

Abstract:
For the past almost fifty years, scientists have been trying to explain the phenomenon of superconductivity. The mechanism is the key ingredient of microscopic theory, which was developed by Bardeen, Cooper, and Schrieffer in 1957. The theory also introduced the basic concepts of pairing, coherence length, energy gap, and so on. Since then, microscopic theory has undergone an intensive development. This book provides a very detailed theoretical treatment of the key mechanisms of superconductivity, including the current state of the art (phonons, magnons, plasmons). In addition, the book contains descriptions of the properties of the key superconducting compounds that are of the most interest for science and applications. For many years, there has been a search for new materials with higher values of the main parameters, such as the critical temperature and critical current. At present, the possibility of observing superconductivity at room temperature has become perfectly realistic. That is why the book is especially concerned with high-Tc systems such as high-Tc oxides, hydrides with record values for critical temperature under high pressure, nanoclusters, and so on. A number of interesting novel superconducting systems have been discovered recently, including topological materials, interface systems, and intercalated graphene. The book contains rigorous derivations based on statistical mechanics and many-body theory. The book also provides qualitative explanations of the main concepts and results. This makes the book accessible and interesting for a broad audience.
