Thermoelectric transport properties in chalcogenides ZnX (X=S, Se): From the role of electron-phonon couplings

Journal of Materiomics, 2021
Electron-phonon coupling (EPC) is a key factor for thermoelectric properties of materials. In this paper, the thermoelectric properties of zinc-blende chalcogenides (p-type) ZnS and ZnSe have been studied through full evaluation of EPC from first ...

Electronic transport in DNA [PDF]

, 2005
We study the electronic properties of DNA by way of a tight-binding model applied to four particular DNA sequences. The charge transfer properties are presented in terms of localization lengths (crudely speaking, the length over which electrons travel).

Electrical properties of Sb and Cr-doped PbZrO3-PbTiO3-PbMg1/3Nb2/3O3 ceramics [PDF]

, 2003
The pyroelectric, dielectric and DC resistive properties of Sb and Cr-doped ceramics with a base composition of Pb(Mg1/3Nb2/3)0.025(Zr0.825Ti0.175)0.975O3 have been studied. Sb doping has been shown to produce a linear reduction in Curie temperature (TC=−

Electrical and Magnetic Transport Properties of Pr0.1Ca0.9MnO3 [PDF]

Advances in Physics Research, 2014
Ceramic Pr1−xCaxMnO3 (x = 0.1) samples were prepared by solid-state reaction and the electrical and magnetic transport properties were studied by direct current (DC) and alternating current (AC) methods in different fields. A Curie temperature of 125 K determined by I-V measurements of ceramic Pr1−xCaxMnO3 (x = 0.1) samples is consistent with that from

Magnetic and electrical transport properties of Pb1-xLaxTi1-xMnxO3 ceramics

AIP Advances, 2012
Pb1-xLaxTi1-xMnxO3 (PLTM100x, x = 0.20, 0.40, 0.50, 0.60, and 0.80) ceramics have been prepared and investigated. X-ray diffractions show all ceramics are crystallized into perovskite structures with tetragonal symmetry for PLTMO20 and orthorhombic ...

Optical and transport properties of polyaniline films [PDF]

, 2002
This thesis presents the results of a comprehensive study on the transport and optical properties of polyaniline (PANI) films. The films are derived by protonation (doping) of the emeraldine base form of polyaniline, as synthesized in Durham, with either

Light-activated modulation and coupling in integrated polymer-liquid crystal systems [PDF]

, 2014
We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device.
