Exercise: Crystal Lattices
Teaching Materials | 29 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise helps the student better understand various types of crystal lattices, in particular diamond and zinc-blende and also helps in better understanding of the miller indicies. The results to some of these problems can be easily arrived at by using the crystal viewer...

Stationary Perturbation Theory: an Exercise for PCPBT
Teaching Materials | 28 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise allows us to test the first and second order stationary perturbation theory and explain mathematically the shift in the energies due to a small perturbation in a quantum well. www.eas.asu.edu/~vasilesk NSF

Quantum-Mechanical Reflections in Nanodevices: an Exercise
Teaching Materials | 02 Jul 2008 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise points out to the fact that quantum-mechanical reflections are going to be significant in nanoscale devices and proper modeling of these device structures must take into consideration the quantum-mechanical reflections. NSF, ONR Dragica Vasileska personal web-site...

From 1 well to 2 wells to 5 wells to periodic potentials: an Exercise
Teaching Materials | 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...

Finite Height Quantum Well: an Exercise for Band Structure
Teaching Materials | 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.
