Abstract
A non-linear theory of acoustoelectric gain and current in piezoelectric semiconductors is developed. An expression is derived for the dependence of the acoustic gain on the amplitude of the wave. A corrected form of the Weinreich relation is also found together with a formula for the effective trapping factor for electrons in the acoustic wave.Keywords
