Electronic aspects of the martensitic transition in Ni-Mn based Heusler alloys
(Elsevier, 2007)
The martensitic transformation temperature Ms depends linearly on the valence electron concentration for Ni-Mn-X Heusler systems where X is a group III-group V element. However, the slopes of the linearity are different ...
The influence of series resistance and interface states on intersecting behavior of I-V characteristics of Al/TiO2/p-Si (MIS) structures at low temperatures
(Iop Publishing Ltd, 2008)
In this study, we have investigated the intersection behavior of the forward bias current-voltage (I-V) characteristics of the Al/TiO2/p-Si (MIS) structures in the temperature range of 100 300 K. The intersection behavior ...
Influence of frequency and bias voltage on dielectric properties and electrical conductivity of Al/TiO2/p-Si/p(+) (MOS) structures
(Iop Publishing Ltd, 2008)
In this study, the frequency and voltage dependence of the dielectric constant (epsilon'), dielectric loss (epsilon ''), loss tangent (tan delta), electric modulus (M' and M '') and ac electrical conductivity (sigma(ac)) ...
A study on the humidity sensing properties of ZnCr2O4-K2CrO4 ionic conductive ceramic sensor
(Elsevier Science Sa, 2006)
The response to humidity of ZnCr2O4-K2CrO4 ceramic composites formed by solid-state reaction at elevated temperatures is studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, ...
Lattice vibrations of pure and doped GaSe
(Pergamon-Elsevier Science Ltd, 2006)
The Bridgman method is used to grow especially undoped and doped single crystals of GaSe. Composition and impurity content of the grown crystals were determined using X-ray fluorescence (XRF) method. X-ray diffraction, ...
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ...
Current-direction-induced rectification effect on (integer) quantized Hall plateaus
(Edp Sciences S A, 2009)
Current distribution across narrow Hall bars in out of linear response regime is studied within a self-consistent Hartree-type mean-field approximation for samples which are equally and unequally depleted laterally. The ...
Interaction-mediated asymmetries of the quantized Hall effect
(Epl Association, European Physical Society, 2009)
Experimental and theoretical investigations on the integer quantized Hall effect in gate-defined narrow Hall bars are presented. At low electron mobility the classical (high-temperature) Hall resistance line R(H)(B) cuts ...
Electrostatic screening and experimental evidence of a topological phase transition in a bulk quantum Hall liquid
(Iop Publishing Ltd, 2009)
The electrostatic screening of a medium disordered quantum Hall liquid was investigated using an electric field penetration (EFP) technique. At sufficiently low temperatures and at magnetic fields corresponding to the ...
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC
(Amer Physical Soc, 2004)
We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter ...
