Electrons and phonons in amorphous semiconductors

K Prasai, P Biswas, DA Drabold - Semiconductor Science and …, 2016 - iopscience.iop.org
The coupling between lattice vibrations and electrons is one of the central concepts of
condensed matter physics. The subject has been deeply studied for crystalline materials, but …

Trapping, self-trapping and the polaron family

AM Stoneham, J Gavartin, AL Shluger… - Journal of Physics …, 2007 - iopscience.iop.org
The earliest ideas of the polaron recognized that the coupling of an electron to ionic
vibrations would affect its apparent mass and could effectively immobilize the carrier (self …

Topics in the theory of amorphous materials

DA Drabold - The European Physical Journal B, 2009 - Springer
In this Colloquium, I describe some current frontiers in the physics of semiconducting
amorphous materials and glasses, including a short, but self-contained discussion of …

Boson peak and Ioffe-Regel criterion in amorphous siliconlike materials: The effect of bond directionality

YM Beltukov, C Fusco, DA Parshin, A Tanguy - Physical Review E, 2016 - APS

analysis of the vibration modes, dynamical structure factor, and energy diffusivity with exact …

Atomistic origin of Urbach tails in amorphous silicon

Y Pan, F Inam, M Zhang, DA Drabold - Physical review letters, 2008 - APS
Exponential band edges have been observed in a variety of materials, both crystalline and
amorphous. In this Letter, we infer the structural origins of these tails in amorphous and …

Hydrodynamic transport in strongly coupled disordered quantum field theories

A Lucas - New Journal of Physics, 2015 - iopscience.iop.org
We compute direct current thermoelectric transport coefficients in strongly coupled quantum
field theories without long lived quasiparticles, at finite temperature and charge density, and …

Connectivity and glass transition in disordered oxide systems

MI Ojovan, WBE Lee - Journal of Non-Crystalline Solids, 2010 - Elsevier
Angell's congruent bond lattice (CBL) model of topologically-disordered oxide systems is
used to analyse the connectivity of disordered systems accounting for the threshold degree …

Multifractal Analysis with the Probability Density Function<? format?> at the Three-Dimensional Anderson Transition

A Rodriguez, LJ Vasquez, RA Römer - Physical review letters, 2009 - APS
The probability density function (PDF) for critical wave function amplitudes is studied in the
three-dimensional Anderson model. We present a formal expression between the PDF and …

Urbach tails of amorphous silicon

DA Drabold, Y Li, B Cai, M Zhang - Physical Review B—Condensed Matter and …, 2011 - APS
In earlier work, we showed that exponential (Urbach) band-edge states were localized on
connected subnetworks of short bonds for the valence tail and long bonds for the conduction …
