General expressions are developed for the dependence of acoustoelectric gain and current on the electron density distribution associated with an acoustic wave propagating through a piezoelectric semiconductor. The results are valid for nearly-periodic travelling waves with arbitrary harmonic content. It is shown that the frequency and magnitude of the peak gain can both tend to zero as the acoustic wave amplitude increases and the electrons bunch more strongly.
