Finite Height Quantum Well: an Exercise for Band Structure
31 Jan 2008 | | Contributor(s):: David K. Ferry
Use the Resonant Tunneling Diodes simulation tool on nanoHUB to explore the effects of finite height quantum wells. Looking at a 2 barrier device, 300 K, no bias, other standard variables, and 3 nm thick barriers and a 7 nm quantum well, determine the energies of the two lowest quasi-bound states.

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 quasi-bound 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...

Quantum Dots
21 Jul 2005 | | Contributor(s):: Gerhard Klimeck
Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such, they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application...
