Research

I am currently working towards a Ph.D. in Electrical Engineering under the direction of my advisor, Prof. Jim Plummer. My reserach is in the general area of novel semiconductor devices. Specifically, right now I am researching band-to-band tunneling (BTBT) as a transport mechanism for low power logic and memory devices. As a fundamentally different carrier transport mechanism than the drift/diffusion found in conventional MOSFETS, BTBT offers the possibility (though not a guarantee) of steeper than kT/q subthreshold transfer characteristics.
