Computational and Experimental Study of Transport in Advanced Silicon Devices
28 Jun 2013   Contributor(s):: Farzin Assad
In this thesis, we study electron transport in advanced silicon devices by focusing on the two most important classes of devices: the bipolar junction transistor (BJT) and the MOSFET. In regards to the BJT, we will compare and assess the solutions of a physically detailed microscopic model to...

Device Physics Studies of IIIV and Silicon MOSFETS for Digital Logic
28 Jun 2013   Contributor(s):: Himadri Pal
IIIV's are currently gaining a lot of attraction as possible MOSFET channel materials due to their high intrinsic mobility. Several challenges, however, need to be overcome before IIIV's can replace silicon (Si) in extremely scaled devices. The effect of low densityofstates of IIIV...
