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

Resumo: No intuito de verificar a existência de correlações supercondutoras em grafite, estudamos a possível existência do fenômeno conhecido como efeito de proximidade gigante em amostras de grafite pirolítica altamente orientada (HOPG). 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. Adicionalmente, realizamos estudos comparativos do efeito de proximidade em bismuto metálico. Discutimos os resultados obtidos em termos de modelos teóricos propostos para este assunto.
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.
