Scattering cross-section — The scattering cross section, sigma; scat, relates the scattering of light or other radiation to the number of particles present. In terms of area, the total cross section ( sigma;) is the sum of the cross sections due to absorption, scattering… … Wikipedia
Scattering theory — Top: the real part of a plane wave travelling upwards. Bottom: The real part of the field after inserting in the path of the plane wave a small transparent disk of index of refraction higher than the index of the surrounding medium. This object… … Wikipedia
Scattering from rough surfaces — Surface roughness scattering or interface roughness scattering is the elastic scattering of a charged particle by an imperfect interface between two different materials. It is an important effect in electronic devices which contain narrow layers … Wikipedia
Length scale — In physics, length scale is a particular length or distance determined with the precision of one order (or a few orders) of magnitude. The concept of length scale is particularly important because physical phenomena of different length scales… … Wikipedia
Small-angle neutron scattering — (SANS) is a laboratory technique, similar to the often complementary techniques of small angle X ray scattering (SAXS) and light scattering. These are particularly useful because of the dramatic increase in forward scattering that occurs at phase … Wikipedia
Biological small-angle scattering — Small angle scattering is a fundamental method for structure analysis of materials, including biological materials. Small angle scattering allows one to study the structure of a variety of objects such as solutions of biological macromolecules,… … Wikipedia
Carrier scattering — Defect types include atom vacancies, adatoms, steps, and kinks which occur most frequently at surfaces due to finite material size causing crystal discontinuity. What all types of defects have in common, whether they be surface or bulk, is that… … Wikipedia
