MATLAB Scripts for "Quantum Transport: Atom to Transistor"
15 Mar 2005   Contributor(s):: Supriyo Datta
Tinker with quantum transport models! Download the MATLAB scripts used to demonstrate the physics described in Supriyo Datta's book Quantum Transport: Atom to Transistor. These simple models are less than a page of code, and yet they reproduce much of the fundamental physics observed in...

MCW07 Electronic Level Alignment at MetalMolecule Contacts with a GW Approach
05 Sep 2007   Contributor(s):: Jeffrey B. Neaton
Most recent theoretical studies of electron transport in singlemolecule junctions rely on a Landauer approach, simplified to treat electronelectron interactions at a meanfield level within density functional theory (DFT). While this framework has proven relatively accurate for certain...

MCW07 Impact of Porphyrin Functional Groups on InAs Gas Sensors
05 Nov 2007   Contributor(s):: Michael Garcia
Porphyrin molecules are often used for sensor engineering to improve sensitivity and selectivity to specific analytes. It is important to understand how the porphyrin HOMOLUMO levels deplete surface states during functionalization of solid state sensors. Additionally, the effect of...

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 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.
