Quantum Wells, Heterostructures and Superlattices
23 Jul 2010 | Teaching Materials | Contributor(s): Stephen M. Goodnick, Dragica Vasileska
this is an overview of the analysis and the application of quantum wells, heterostructures and superlattices.
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...
Energy Bands as a Function of the Geometry of the n-Well Potential: an Exercise
0.0 out of 5 stars
05 Jul 2008 | Teaching Materials | Contributor(s): Dragica Vasileska, Gerhard Klimeck
Explores the position and the width of the bands as a function of the 10-barrier potential parameters.
Bound States Calculation Description
05 Jul 2008 | Teaching Materials | 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...
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...
