The Capture of Electrons by Negatively Charged Impurity Atoms in N-Type Germanium

It is well known that the capture of an electron by an impurity atom is governed by two factors; (1) the electric charge on the impurity atom, and (2) the way in which the electron loses energy in its transition from the conduction band to a captured state. We have studied the dependence of capture rate on the external electric field at law temperature (20°K) for n-Ge containing gold centres as impurities.
