My research interests are in Theoretical & Computational
Materials Physics, with an emphasis on the microscopic physics
properties of semiconductor materials. Over the years, I have worked on
a variety of problems in high electric field transport,
electronic properties of defects, electronic bandstructures,
vibrational properties, & electronic & structural properties of
semiconductor alloys.
In the past, much of my work used semiempirical methods, along
with tightbinding bandstructures to study various properties
of several different semiconductor materials.
Presently, the main computational tools I use are Molecular Dynamics
simulations, Monte Carlo simulations, & first-principles (ab-initio)
density
functional-based electronic structure techniques.
Currently, my main interests are in the following Diverse
Areas: 1)Computing
the structural, electronic, vibrational & transport properties of
Thermoelectric Materials (materials which show promise for
thermoelectric applications). Among the materials of interest are Clathrate
& Skutterudite Semiconductor Materials.
2)Studying
high electric field transport
in GaAs& other
semiconductor materials with the primary goal of understanding
photoconductive Semiconductor
Switch Behavior.
