My research interests are in theoretical and computational materials (condensed matter) physics, with emphasis on understanding the microscopic physics of semiconductor materials. Current problems of interest are divided into two categories. 1) The use of ab-initio and semi-empirical methods to study the structural, electronic, vibrational, and thermodynamic properties of solids which show promise as thermoelectric materials. Two types of materials of interest in this regard are the semiconductor clathrates and the skudderudites. 2) The use of high field transport and Monte Carlo simulation techniques to study the high electric field behavior of gallium arsenide and related materials, with applications to understanding the behavior of photoconductive semiconductor switches.
