Abstract
Abstract Acoustoelectronics is based both in its conceptional and experimental aspects on the piezoelectric effect discovered by J. Curie and P. Curie. This paper reviews the research on acoustoelectronics which has been carried out at A. F. loffe Physico-Technical Institute in Leningrad. Three basic types of acoustoelectron interactions are considered: (i) interaction of bulk acoustic waves in a piezoelectric semiconductor with free charge carriers; (ii) interaction of surface acoustic waves in a piezodielectric crystal with free carriers in an adjacent semiconductor and (iii) interaction of surface acoustic waves in a piezoelectric crystal with free electrons in vacuum. The main characteristic features of the acoustoelectron interactions are illustrated by the experimental results obtained with well known piezoelectric crystals such as CdS, Te, InSb, SiO2, LiNbO3. Both linear and nonlinear acoustoelectron effects are described.
