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 ...
Extended investigation of intermartensitic transitions in Ni-Mn-Ga magnetic shape memory alloys: A detailed phase diagram determination
(Amer Inst Physics, 2013)
Martensitic transitions in shape memory Ni-Mn-Ga Heusler alloys take place between a high temperature austenite and a low temperature martensite phase. However, intermartensitic transformations have also been encountered ...
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)) ...
Production and characterization of liquid crystal/polyacrylonitrile nano-fibers by electrospinning method
(Springer Link, 2021)
We present that high birefringent nematic liquid crystal, 4-n-pentyl-4'-cyanobiphenyl, was incorporated into the polyacrylonitrile precursor which has a strong polar cyano group so as to produce electrospun nano-fibers, ...
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, ...
Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
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 ...
Temperature dependent symmetry to asymmetry transition in wide quantum wells
(Elsevier, 2015)
Quasi-two dimensional electron systems exhibit peculiar transport effects depending on their density profiles and temperature. A usual two dimensional electron system is assumed to have a 6 like density distribution along ...
