Band structure error in InAs UTB devices
Closed  Responses: 0
Dear Sir/Madam,
first of all, I would like to thank you to have developed and made available online this tool.
Currently, I’m interested in the study of the band structure of http://nanohub.org/answers/question/1328

What would be the electron effective mass of InAs in its electron valleys in X,Y,Z directions?
Open  Responses: 1
The default values in the Multi gate Nanowire tool for Si effective mass in Valley 1,2,3 in x,y,z directions are
0.19,0.19,0.98; 0.19,0.98,0.19; 0.98,0.19,0.19 respectively.

Atomistic Alloy Disorder in Nanostructures
26 Feb 2007   Contributor(s):: Gerhard Klimeck
Electronic structure and quantum transport simulations are typically performed in perfectly ordered semiconductor structures. Bands and modes are defined resulting in quantized conduction and discrete states. But what if the material is fundamentally disordered? What if the disorder is at the...

Band Structure Calculation: General Considerations
17 May 2010   Contributor(s):: Dragica Vasileska
This set of slides explains to the users the concept of valence vs. core electrons, the implications of the adiabatic approximation on the separation of the total Hamiltonian of the system and the meanfield approximation used in ab initio bandstructure approaches. It then gives systematic...
