Abstract:
Transparent 3Na2O–6.5B2O3 (NBO) glasses were fabricated via the conventional melt-quenching technique. X-ray powder diffraction (XRD) combined with Differential Scanning Calorimetric (DSC) studies carried out on the as-quenched samples confirmed their amorphous and glassy nature, respectively. The frequency and temperature dependent of the dielectric constant, electric modulus and electrical conductivity of the transparent NBO glasses were investigated in the 100 Hz–10 MHz frequency range. The electrical modulus and conductivity data have been rationalized using Jonscher's universal law. The b

In dielectric science, the electrical breakdown strength of a polymeric material significantly decreases with elevated temperatures, which restricts the development of advanced electrical and electronic applications toward miniaturization.

An experimental study of the temperature dependent dc electrical conductivity of doped poly (p-phenylene) in the range of 50-300 K has been presented.

We have observed that hopping models are not consistent with the temperature dependence of the conductivity data over the entire temperature range of measurement. We find that the logarithmic conductivity is proportional to Tβ, where the exponent β is independent of temperature.

The electronic transport theory predicts linear temperature dependences for the thermopower (S) and the electrical resistivity (ρ) at elevated temperatures. However, the experimental data for La x Y 1− x Al 2 alloys reveal nonlinear dependences for both, S(T) and ρ (T) . We relate this disagreement to the density of states (DOS) structure in the vicinity of the Fermi level. Based on the linearised Boltzmann transport equation, we obtain from the experimental temperature dependences of ρ and S an electron dependent function ϕ(ε), reflecting the energy dependence of DOS and that of scattering pr

Abstract:
Bismuth nanowires are excellent model systems to investigate the interplay of various size-dependent transport phenomena relevant for applications in thermoelectrics, spintronics or catalytics. Due to the large Fermi wavelength (lFermi~40 nm) and mean free paths of charge carriers (le and lph ~100 nm) in bismuth at room temperature, the influence of size-effects on the transport properties can be observed on nanowires of rather large diameters. Furthermore, these properties are also influenced by the fact that bismuth belongs to the class of topological insulator materials that exhibit special

In the present paper, the ternary system 0.90 BaTiO3-0.07 BiFeO3-0.03 CaSnO3 (referred as BTO-BFO-CSO-3) near the morphotropic phase boundary (MPB) was synthesized via a cost effective mixed-oxide route and sintered at 1050?C. Phase composition analysis confirms that the sample crystallizes in orthorhombic phase with few impurity peaks. Room temperature Raman spectrumdepicts the phonon peaks characteristic for BTO-BFOCSO-3 structure. Microstructural examination by scanning electron microscope shows the uniform distribution of grains on the surface of the density sample. The capacitive and resi

Simultaneous ZnSe nanowire growth and p-type doping is realized in one step by using Bi as the catalyst and dopant via chemical vapor deposition. Temperature-dependent electrical measurements are used for understanding the charge transport mechanism and the doping effect.

Abstract:
Electrical conductivity and acoustic loss Q−1 of single crystalline Li(Nb,Ta)O3 solid solutions (LNT) are studied as a function of temperature by means of impedance spectroscopy and resonant piezoelectric spectroscopy, respectively. For this purpose, bulk acoustic wave resonators with two different Nb/Ta ratios are investigated. The obtained results are compared to those previously reported for congruent LiNbO3. The temperature dependent electrical conductivity of LNT and LiNbO3 show similar behavior in air at high temperatures from 400 to 700 °C. Therefore, it is concluded that the dominant t

Abstract:
Abstract As a promising platform for unconventional superconductivity, Josephson junctions (JJs) of tetradymite topological insulators (TIs) and s-wave superconductors have been investigated in recent years. This family of TI materials, however, often suffers from spurious bulk transport, which hampers the observation of the exotic physics of their topological surface states. Thus, disentangling the transport mechanism of bulk and surface contributions in TI JJs is of high importance when investigating proximity induced superconductivity in those crystals. In this work, we add to the insights

Abstract:
We investigated the temperature-dependent reverse characteristics (JR-VR-T) of vertical GaN Schottky-barrier diodes with and without a fluorine-implanted edge termination (ET). To understand the device leakage mechanism, temperature-dependent characterizations were performed, and the observed reverse current was modeled through technology computer-aided design. Different levels of current were observed in both forward and reverse biases for the ET and non-ET devices, which suggested a change in the conduction mechanism for the observed leakages.

Polycrystalline samples of double layered (DL) manganite system La 1.2( Sr 1-x Ba x)1.8 Mn 2 O 7(0.0≤×≤0.4) were prepared by the sol-gel method. The anisotropic lattice expansion is observed with the substitution of Ba 2+ into Sr 2+ sites. The electrical resistivity and magnetoresistance (MR) measurements were carried out over the temperature range 4.2 K–300 K. The substitution of Ba results in the suppression of T IM , insulator-to-metal transition temperature. A low temperature upturn of resistivity is seen in all the samples of the system, which is attributed to the spin-glass-like transiti
