Abstract

A simple new method is described for probing acoustoelectric domains in n-GaAs through their strong photoconductive response to a focused light beam. This permits a scan of the spatial distribution and propagation of the amplified acoustic flux in the sample. As a further application of the photoconductive response, a narrow propagating domain can be used to reveal an optical image projected onto the sample. The techniques are illustrated here primarily for extrinsic photoexcitation with Nd:YAG laser light.
