20 Jul 2010 | Contributor(s): David K. Ferry, Dragica Vasileska
This set of slides describes in detail the derivation of Fermi's Golden Rule.
This set of slides describes the derivation of Fermi-Dirac, Maxwell-Boltzmann and Bose-Einstein statistics.
Explanation of Rode's Iterative Procedure
This set of slides describes the Rode's iterative procedure for the mobility calculation when the scattering mechanisms are neither elastic nor isotropic such as is polar optical phonon scattering.
Crystal Directions and Miller Indices
08 Jun 2010 | Contributor(s): David K. Ferry, Dragica Vasileska, Gerhard Klimeck
Miller indices are a notation system in crystallography for planes and directions in crystal lattices. In particular, a family of lattice planes is determined by three integers, l, m, and n, the Miller indices. They are written (lmn) and denote planes orthogonal to a direction (l,m,n) in the...
In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a basis, a set of atoms arranged in a particular way, and a lattice. The basis is located upon the points of a lattice spanned by lattice vectors, which is an...

Homework Assignment: Periodic Potentials
31 Jan 2008 | Teaching Materials | Contributor(s): David K. Ferry
Using the Periodic Potential Lab on nanoHUB determine the allowed bands for an energy barrier of 5 eV, a periodicity W = 0.5nm, and a barrier thickness of 0.1nm. How do these bands change if the barrier thickness is changed to 0.2 nm?
Finite Height Quantum Well: an Exercise for Band Structure
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.
MOSfet Homework Assignment - Role of Dielectric Constant and Thickness
Use the MOSfet tool on nanoHUB to simulate a n-channel MOSFET with the following parameters:Lsd=LG=45nm (each 15 nodes), oxide thickness of 1.2 nm (K=3.9, 5 nodes),poly-Si gate, junction depth of 10 nm (20 nodes), and all other parametersat their nominal preset values.Now, change K to 20, and...
