Nanodevices come in many shapes and sizes, and are based on a number of different materials. There is an exciting effort world wide to exploit advances in nanotechnology to build the next generation of device technologies for applications in Energy, Information and Communication Technology, Medicine and so on. One problem though is that there are a plethora of nano- materials and device ideas. Rather than take a try-everthing Edisonian approach, a more systematic approach based on coupling Theory and Modeling to Experiments has potential to isolate the more promising nanodevices, apart from of course leading to a more thorough understanding of the underlying device physics (and hence saving cost in development).

Our group primarily focuses on a variety of problems in the theory and modeling of semiconductor, molecular and bionano devices/structures, using primarily quantum and some semiclassical approaches. Our work includes the electrical, optical and electromechanical properties. Typical projects may include theoretical work or large-scale computational modeling on multiple processors. The projects may either be purely academic or may have an industrial focus depending on the funding sources and collaborations.

Some of our recent / on-going projects include:

• Charge transport in DNA
• Design of photodetectors and imagers
• Electromechanical response of nanostructures

• Nanowires and Nanotubes (devices & fundamental properties)

• Nanotransistors

• Methods to compute charge and electron densities
