Uniform versus delta doping in 1D heterostructures: an Exercise
15 Aug 2008   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   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...

Quantum Mechanics: Hydrogen Atom
09 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The solution of the Schrödinger equation (wave equations) for the hydrogen atom uses the fact that the Coulomb potential produced by the nucleus is isotropic (it is radially symmetric in space and only depends on the distance to the nucleus). Although the resulting energy eigenfunctions (the...

Quantum Mechanics for Engineers: Podcasts
07 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck, David K. Ferry
