Scattering of band carriers by neutral and charged impurities
Mobility of band carriers scattered on donors, partially ionized, partially neutral, is considered in general and calculated for crystals belonging to AIII-BV group. As neutral impurity we have constructed the hydrogen-like model. It is shown that dependence of mobility on temperature is determined by relation between number of ionized and neutral donors and by average energy of electrons.
