Uniform versus delta doping in 1D heterostructures: an Exercise
15 Aug 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise is designed to demonstrate that delta doping leads to larger sheet electron density in the channel and it also allows for better control of the charge density in the channel region of High Electron Mobility Transistors (HEMTs).

Parallel Conduction Channel: an Exercise for 1D Heterostructure Lab
15 Aug 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise uses the 1D Heterostructure Lab, which demonstrates that adding more dopants in the buffer layer becomes ineffective after certain critical doping density. Beyond this critical doping density, additional dopants practically fill in the parallel conduction channel that sits in the AlGaAs layer in which carriers have significantly lower mobility due to alloy scattering.

Bulk Band Structure: a Simulation Exercise
03 Aug 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This simulation exercise teaches the students about band structure of indirect and direct bandgap materials, the optical gaps, the concept of the effective mass and the influence of spinorbit coupling on the valence bandstructure.

BJT  Simulation Exercise
03 Aug 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This simulation exercise teaches the students the operation of BJT transistor, what is current gain and how one extracts current gain from the Gummel plot. It also provides output device characteristics from which students have to extract the Early voltage. Furthermore, it makes the students explore alternative dimensions for which one can get higher current gain and higher Early voltage. Overall, it is excellent introductory exercise to basic BJT transistor operation.NSF
