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 materials...

Simulation of highly idealized, atomic scale MQCA logic circuits
15 Nov 2007   Contributor(s):: Dmitri Nikonov, George Bourianoff
Spintronics logic devices based on majority gates formed by atomiclevel arrangements of spins in the crystal lattice is considered. The dynamics of switching is modeled by timedependent solution of the densitymatrix equation with relaxation. The devices are shown to satisfy requirements for...

TwoDimensional Scattering Matrix Simulations of Si MOSFET'S
27 Jun 2013   Contributor(s):: Carl R. Huster
For many years now, solid state device simulators have been based on the driftdiffusion equations. As transistor sizes have been reduced, there has been considerable concern about the predictive capability of these simulators. This concern has lead to the development of a number of simulation...
