AQME assembles a set of nanoHUB tools that we believe are of immediate interest for the teaching of quantum mechanics class for both Engineers and Physicists. Users no longer have to search the nanoHUB to find the appropriate applications for this particular purpose. This curated page provides a “on-stop-shop” access to associated materials such as homework or project assignments.
Quantum Mechanics: Introductory Concepts
out of 5 stars
07 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck, David K. Ferry
In this section of the Quantum Mechanics class we discuss the particle-wave duality and the need for the quantization of energy to explain the black-body radiation and the photoelectric effect. We provide reading material, slides and video, which in a very illustrative way, explain the most...

Quantum Mechanics: Postulates
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
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...

Periodic Potentials and the Kronig-Penney Model
01 Jul 2008 | | Contributor(s):: Dragica Vasileska
This material describes the derivation of the Kronig-Penney model for delta-function periodic potentials.
Quantum-Mechanical Reflections in Nanodevices: an Exercise
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, ONRDragica Vasileska personal web-site...
Periodic Potentials and Bandstructure: an Exercise
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
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 the...
30 Jun 2008 | | Contributor(s):: Dragica Vasileska
This tutorial contains introductory material for Quantum Mechanics for Engineers with emphasis on tunneling, open systems and the definitions of transmission and reflection coefficients and their calculation in the case of piece-wise constant potential energy profiles.NSF
Double Barrier Case
This material contains derivation for the transmission coefficient and current calculation in double-barrier structures that are also known as resonant tunneling diodes.
