Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called diffuse reflections and unscattered reflections are called specular(mirror-like) reflections.

Atomistic Green’s Functions: The Beauty of Self-energies
28 Oct 2020 | | Contributor(s):: Tillmann Christoph Kubis
This presentation gives an introduction to NEGF. It will be explained how self-energies cause NEGF to fundamentally differ from most other quantum methods. Atomistic examples of phonon and impurity scattering self-energies agree quantitatively with experiments.

Carbon Nanotube Electronics: Modeling, Physics, and Applications
27 Jun 2013 | | Contributor(s):: Jing Guo
In recent years, significant progress in understanding the physics of carbon nanotube electronic devices and in identifying potential applications has occurred. In a nanotube, low bias transport can be nearly ballistic across distances of several hundred nanometers. Deposition of high-k gate...
Modeling Quantum Transport in Nanoscale Transistors
27 Jun 2013 | | Contributor(s):: Ramesh Venugopal
As critical transistor dimensions scale below the 100 nm (nanoscale) regime, quantum mechanical effects begin to manifest themselves and affect important device performance metrics. Therefore, simulation tools which can be applied to design nanoscale transistors in the future, require new theory...
Two-Dimensional Scattering Matrix Simulations of Si MOSFET'S
27 Jun 2013 | | Contributor(s):: Carl R. Huster
For many years now, solid state device simulators have been based on the drift-diffusion equations. As transistor sizes have been reduced, there has been considerable concern about the predictive capability of these simulators. This concern has lead to the development of a number of simulation...

Dissipative Quantum Transport in Semiconductor Nanostructures
23 Dec 2011 | | Contributor(s):: Peter Greck
In this work, we investigate dissipative quantum transport properties of an open system. After presenting the background of ballistic quantum transport calculations, a simple scattering mechanism, called Büttiker Probes, is introduced. Then, we assess the properties of the Büttiker Probe model...
