  1. 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...
