Research

Publications Group Conferences

 

We are a semiconductors devices group.  Our primary goal is to make new devices to exploit, and understand new physics.  This approach leads us naturally to explore some of the fundamental limits of semiconductor devices.  In recent years, we are immersed in research on the following topics (in collaboration with Prof. Xing’s group):

-       the performance limits of ultrahigh speed GaN transistors,

-       wide bandgap semiconductor transistors for power electronics (see Energy.gov presentation),

-       all-electronic THz sources,

-       ultra-low power sub-Boltzmann switching transistors by tunneling and other correlated mechanisms,

-       deep-UV LEDs and lasers approaching 200 nm using quantum dots, and

-       extreme-electron concentration devices in oxides.

 

Often this research path requires us to explore new materials.  We grow the new materials by ourselves using Molecular Beam Epitaxy (MBE), or work very closely with groups that do.  Currently the materials families we are investigating for the above devices are: Nitride Semiconductors, Graphene & 2D Crystals, and Oxide Semiconductors.

 

The goal to make devices also requires, or results in, a deep theoretical understanding of electron transport, electron-phonon interactions, light-matter interactions, geometric and topological aspects of condensed matter physics, and correlated electron physics.  We do a significant amount of theory and modeling ourselves, and work closely with theoreticians when things get out of our reach.

Outreach

I enjoy sharing the joy of the history of science and mathematics.

 

The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce and gives it some of the grace of tragedy. – Steven Weinberg
