Description

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.

  4. IWCN 2021: How to Preserve the Kramers-Kronig Relation in Inelastic Atomistic Quantum Transport Calculations

    Online Presentations | 15 Jul 2021 | Contributor(s):: Daniel Alberto Lemus, James Charles, Tillmann Christoph Kubis

    The nonequilibrium Green’s function method (NEGF) is often used to predict quantum transport in atomically resolved nanodevices. This yields a high numerical load when inelastic scattering is included. Atomistic NEGF had been regularly applied on nanodevices, such as nanotransistors....

  6. Atomistic Green’s Functions: The Beauty of Self-energies

    Online Presentations | 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.

  8. Disordered Photonics

    Online Presentations | 11 Apr 2014 | Contributor(s):: Hui Cao

    Most of the research in the field of photonics has focused on understanding and mitigating the effects of disorder which are often detrimental. For certain applications, however, intentionally introducing disorder can actually improve the device performance, e.g., in photovoltaics optical...
