Direct electromegnetic generation of high frequency acoustic waves in semiconductor superlattices
Abstract
The periodic space charge layers formed in semiconducting superlattice structures can be used for direct electromagnetic generation of high frequency acoustic waves. The mechanism for and resonant nature of the acoustic generation are discussed. © 1983.
