A propagating acoustic wave in a piezoelectric semiconductor suffers a damping engendered by interaction with conduction electrons. The mechanism of this damping is studied, with particular regard to its effect on acoustic resonance and thus on electric impedance. Explicit relations for electric impedance near acoustic resonance are given. Specific numerical examples for electrical impedance near longitudinal mode acoustic resonance are given for cadmium sulphide and zinc oxide. Author-PL.
