Nanoelectronic Modeling Lecture 14: Open 1D Systems  Formation of Bandstructure
25 Jan 2010   Contributor(s):: Gerhard Klimeck, Dragica Vasileska
The infinite periodic structure Kroenig Penney model is often used to introduce students to the concept of bandstructure formation. It is analytically solvable for linear potentials and shows critical elements of bandstructure formation such as core bands and different effective masses in...

Nanoelectronic Modeling Lecture 12: Open 1D Systems  Transmission through Double Barrier Structures  Resonant Tunneling
25 Jan 2010   Contributor(s):: Gerhard Klimeck, Dragica Vasileska
This presentation shows that double barrier structures can show unity transmission for energies BELOW the barrier height, resulting in resonant tunneling. The resonance can be associated with a quasi bound state, and the bound state can be related to a simple particle in a box calculation.

Nanoelectronic Modeling Lecture 08: Introduction to Bandstructure Engineering II
30 Dec 2009   Contributor(s):: Gerhard Klimeck
This presentation provides a brief overview of the concepts of bandstructure engineering and its potential applications to light detectors, light emitters, and electron transport devices. Critical questions of the origin of bandstructure and its dependence on local atom arrangements are raised...

Nanoelectronic Modeling Lecture 07: Introduction to Bandstructure Engineering I
30 Dec 2009   Contributor(s):: Gerhard Klimeck
This presentation serves as a reminder about basic quantum mechanical principles without any real math. The presentation reviews critical properties of classical systems that can be described as particles, propagating waves, standing waves, and chromatography.
