Electrical transport properties of III-nitrides

Materials Science and Engineering: B, 1997
Abstract Excellent n-type GaN layers have been grown by all of the major epitaxial techniques: MBE, MOCVD, and HVPE. In this work, we analyze the band conduction in such samples by temperature-dependent Hall-effect measurement and theory, and determine quantitative information on donor and acceptor concentrations, as well as donor activation energies.

Electrical transport properties and crystal structure of LiZnAs

Physical Review B, 1987
The first report on the electrical transport properties of LiZnAs is presented. LiZnAs, which has an antifluorite structure, is a p-type semiconductor with energy band gap of about 1.1 eV. The intrinsic region is found at temperatures above 450 K. The typical resistivity, Hall mobility, and carrier concentration at room temperature are of the order of $

Electrical-transport properties in the semimetallic compound LiGa

Physical Review B, 1986
The temperature-dependent electrical resistivity above 15 K and the room-temperature Hall coefficient of Li-Ga are presented for five different Li concentrations. The temperature-dependent part of the resistivity is independent of the Li concentration. However, the residual resistivity increases very rapidly with increasing Li concentration.

Electrical Transport Properties of Polymorphic MoS₂

ACS Nano, 2016
The engineering of polymorphs in two-dimensional layered materials has recently attracted significant interest. Although the semiconducting (2H) and metallic (1T) phases are known to be stable in thin-film MoTe2, semiconducting 2H-MoS2 is locally converted into metallic 1T-MoS2 through chemical lithiation.

Electrical transport properties of a supramolecular assembly

Inorganic Chemistry Communications, 2001
Abstract The direct current conductivity of the urea–[Cu I L 2 ]PF 6 supramolecular assembly ( 1 ) has been measured in the temperature range 24–118°C. It is found that 1 behaves as a semiconductor in 24–33°C, as a metal in 33–63°C and again as a semiconductor in 63–118°C.

Dielectric and electrical transport properties of biopolymers

SPIE Proceedings, 2007
A new capacitive test structure is used to characterize biopolymers at microwave frequencies. The new test structure is comprised of a parallel plate capacitor, combined with coplanar waveguide-based input and output feed lines. This allows electrical measurements to be taken easily under an applied DC electric field and at various temperatures. The

Magnetic and electrical transport properties of Ce5RhGe2

Journal of Alloys and Compounds, 2019
Abstract We report a comprehensive investigations of the electronic structure and magnetic properties for Ce5RhGe2, that crystallizes in orthorhombic Y2HfS5-type structure. This novel phase was found to be ferromagnetic-type with the Curie temperature T C of 11.5 K in coexistence with spin-glass-like phase, displayed in the magnetic

Electrical Transport Properties of p-GaN

Japanese Journal of Applied Physics, 1996
Electrical transport properties of Mg-doped p-GaN grown by organometallic vapor phase epitaxy were studied between 100 and 700 K. Calculations using Fermi-Dirac statistigs were carried out, identifying the majority carrier to be holes over the whole temperature range considered. The acceptor level is 0.17 ± 0.01 eV.

Magnetic, Electric and Transport Properties

2010
Some properties of liquid crystals depend mainly on properties of individual molecules and approximately obey the additivity law. Thus, molecular properties can be translated, of course with some precautions, onto the properties of a mesophase on account of the symmetry of the latter.

Magnetic and Electric Effects on Transport Properties

Annual Review of Physical Chemistry, 1970
with an introdu ctory section in which the recent history of the subject is presented along with a short outline of the underlying physics. A survey of the principal developments will then be given. In order to facilitate the review procedure, the subject matter will be sub divided in the following manner: the influence of a static magnetic field on ...
