nanoHUB - Educational Tour de Force

14 Jan 2016 | Online Presentations | Contributor(s): David K. Ferry

nanoHUB was originally created to bring together the computational electronics world as a place where programs and results could be efficiently shared. For that purpose, it has matured and grown to where it is a major force in the area. But, it can also be a great tool for education, an...

Using NanoHub in Undergraduate Education

25 Jun 2014 | Online Presentations | Contributor(s): David K. Ferry

nanoHUB.org has now been with us for quite some time. It has developed a suite of software simulation tools that is used extensively throughout the research community around the world. Some years back, I was tasked to find a way to create a laboratory for our course on “Electronic Materials and...

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 | Teaching Materials | 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...

Crystal Structures

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...

We describe the development of the modeling efforts focused towards proper description of the threshold voltage fluctuations due to the discrete impurity effects (different number and different distribution of the impurities from device to device on the same chip).NSF, ONRW. J. Gross, D....

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.
