Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009  Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phononlimited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in nonconfined ones.

Energy Bands as a Function of the Geometry of the nWell Potential: an Exercise
05 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
Explores the position and the width of the bands as a function of the 10barrier potential parameters.NSF

Bound States Calculation Description
05 Jul 2008   Contributor(s):: Dragica Vasileska
These lectures describe the calculation of the bound states in an infinite potential well, finite potential well and triangular well approximation. At the end, shooting method, that is used to numerically solve the 1D Schrodinger equation, is briefly described.visit www.eas.asu.edu/~vasileskNSF

From 1 well to 2 wells to 5 wells to periodic potentials: an Exercise
02 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise demonstrates that the interaction between the wells lifts the degeneracy of the quasibound states and if in the limit we have infinite periodic potential it leads to formation of energy bands. Notice that when the interaction is less strong the energy levels are more sharp and the...
