A Tutorial for Nanoelectronics Simulation Tools
03 Jul 2007   Contributor(s):: James K Fodor, Jing Guo
This learning module introduces nanoHUB users to some of the available simulators. The simulators discussed are FETToy, nanoMOS, Schred, CNTbands, and QDot Lab. For each simulator, a brief introduction to the simulator is presented, followed by voiced presentations featuring the simulator in...

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...

Bandstructure Effects in Nano Devices With NEMO: from Basic Physics to Real Devices and to Global Impact on nanoHUB.org
08 Mar 2019   Contributor(s):: Gerhard Klimeck
This presentation will intuitively describe how bandstructure is modified at the nanometer scale and what some of the consequences are on the device performance.

Bandstructure in Nanoelectronics
01 Nov 2005   Contributor(s):: Gerhard Klimeck
This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling...

Comparison of PCPBT Lab and Periodic Potential Lab
04 Aug 2009   Contributor(s):: Abhijeet Paul, Samarth Agarwal, Gerhard Klimeck, Junzhe Geng
This small presentation provides information about the comparison performed for quantum wells made of GaAs and InAs in two different tools. This has been done to benchmark the results from completely two different sets of tools and validate the obtained results. In this presentation we provide...
