Abstract
Acoustoelectric signals in semiconductors induced by a pulsed laser beam are analyzed theoretically and measured experimentally. These signals result from two interactions: photoacoustic in a piezoelectric material illuminated by the laser beam and acoustoelectric in a semiconductor coupled with the piezoelectric body through an air gap
