Abstract

Ultrahigh-frequency (up to 24 GHz) surface acoustic waves were excited with short-period interdigital transducers and detected in GaAs/AlGaAs quantum wells with an optical scheme. We demonstrate that the transducers can be driven in a contactless fashion. Sets of two transducers permitted the coherent emission of surface acoustic waves and the creation of standing waves due to interference. The ...
