Abstract
It is shown that the amplification coefficient of sound with a wave vector corresponding to a Brillouin zone edge of a superlattice structure containing at least one piezoelectric component is resonantly enhanced with respect to other wave vectors in the presence of an electron drift velocity which exceeds the sound velocity.Keywords
