Bulk Monte Carlo Code Described
01 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska
In this tutorial we give implementation details for the bulk Monte Carlo code for calculating the electron drift velocity, velocityfield characteristics and average carrier energy in bulk GaAs materials. Identical concepts with minor details apply to the development of a bulk Monte Carlo code for Si.

QuantumMechanical Reflections in Nanodevices: an Exercise
02 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise points out to the fact that quantummechanical reflections are going to be significant in nanoscale devices and proper modeling of these device structures must take into consideration the quantummechanical reflections.

Periodic Potentials and Bandstructure: an Exercise
02 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise teaches the students that in the case of strong coupling between the neighboring wells in square and Coulomb periodic potential wells electrons start to behave as free electrons and the gaps that open at the Brillouin zone boundaries become smaller and smaller (thus recovering the free particles dispersion relation).

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 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 width of the bands is smaller.

Exercise: CV curves for MOS capacitors
02 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise demonstrates to the students how the lowfrequency CV curves in MOS capacitors change with changing the gate workfunction, the oxide thickness and the dielectric constant. It also demonstrates the doping variation of the highfrequency CV curves.NSFNSF
