Quantum Mechanics: Introductory Concepts
07 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck, David K. Ferry
In this section of the Quantum Mechanics class we discuss the particlewave duality and the need for the quantization of energy to explain the blackbody radiation and the photoelectric effect. We provide reading material, slides and video, which in a very illustrative way, explain the most...

Quantum Mechanics: Postulates
07 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
A physical system is generally described by three basic ingredients: states; observables; and dynamics (or law of time evolution) or, more generally, a group of physical symmetries. A classical description can be given in a fairly direct way by a phase space model of mechanics: states are points...

Quantum Mechanics: Wavepackets
07 Jul 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
In physics, a wave packet is an envelope or packet containing an arbitrary number of wave forms. In quantum mechanics the wave packet is ascribed a special significance: it is interpreted to be a "probability wave" describing the probability that a particle or particles in a particular state...

This material describes the derivation of the KronigPenney model for deltafunction periodic potentials.

QuantumMechanical Reflections in Nanodevices: an Exercise
02 Jul 2008   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.NSF, ONRDragica Vasileska personal website...

Periodic Potentials and Bandstructure: an Exercise
02 Jul 2008   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...

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...
