Abstract
The interaction of the surface acoustic wave (SAW) with the GaAs/AlAs superlattice is investigated using a separate-medium convolver structure. The magnitude and polarity of the acoustoelectric voltages exhibit strong temperature and SAW frequency dependences, a phenomenon that is not observed in homogeneous semiconductors. Possible SAW-superlattice interaction models that tentatively explain the observed data are discussed.Keywords
