Parallel Conduction Channel: an Exercise for 1D Heterostructure Lab
Teaching Materials | 15 Aug 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise uses the 1-D 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...
