Notes on Scattering and Mobility in 1D, 2D, and 3D

06 Nov 2009 | Teaching Materials | Contributor(s): Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff

Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) or quantum confined (2D and 1D) semiconductor structures. Analytical estimates are made that show the mobility in …

From 1 well to 2 wells to 5 wells to periodic potentials: an Exercise

02 Jul 2008 | Teaching Materials | Contributor(s): Dragica Vasileska, Gerhard Klimeck

This exercise demonstrates that the interaction between the wells lifts the degeneracy of the quasi-bound states and if in the limit we have infinite periodic potential it leads to formation of …
