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.

Phonon Interactions in Single-Dopant-Based Transistors: Temperature and Size Dependence
25 Nov 2015 | | Contributor(s):: Marc Bescond, Nicolas Cavassilas, Salim Berrada
IWCE 2015 presentation. in this work we investigate the dependence of electron-phonon scattering in single dopant-based nanowire transistor with respect to temperature and dimensions. we use a 3d real-space non-equilibrium green': ; s function (negf) approach where electron-phonon...
