BJT Lab: FirstTime User Guide
15 Jun 2009  Teaching Materials  Contributor(s): Saumitra Raj Mehrotra, Benjamin P Haley
This firsttime user guide provides introductory material to BJT on nanoHUB. It includes a tour of the Rappture interface, which notes key inputs and typical outputs, and an introduction to the workings of NPN and PNP type BJT. We discuss the default simulation (what happens if you don't change any inputs, and just hit "Simulate") as well as the limitations of the tool. Provided also are a few examples that allow the users to understand the scope of the tool. Lastly, we offer final comments …

Carrier Statistics  Temperature Effects
10 Aug 2010  Teaching Materials  Contributor(s): Saumitra Raj Mehrotra, Dragica Vasileska, Gerhard Klimeck
Silicon (Si), Germanium (Ge) and GalliumArsenide (GaAs) are commonly used materials for MOS Field Effect Transistor (MOSFET) fabrication. MOSFET structures are commonly doped to achieve the desired switching operation and doping is a critical parameter in MOSFET designing.
The goal in this test is to calculate the temperature range of device operation using Si,Ge and GaAs materials.
