Term (Index) Definition
drift velocity  velocity of charge carriers in semiconductor under the influence of electric field; as opposed to carriers in free space carriers in semiconductor are not "infinitely" accelerated by the electric field because of the scattering, and thus, they reach a finite velocity regardless of the period of time over which the field is acting; at a given electric field drift velocity is determined by the mobility of charge carrier.
drift current  current in semiconductor caused by electric field.
scattering  process responsible for electron in a certain state, defined by its crystal momentum, suddenly moving into a different state; result of interactions with host atoms in the lattice, dopant atoms, as well defects; fundamental effect defining electron transport in semiconductor; in a way scattering can be seen as a "collision" during which species do not come to physical contact.
drift mobility  a proportionality factor between drift velocity of charge carriers in semiconductor and electric field.
