Electromechanical Conversion in MS-Contacts; Determination of Frequency Response, Depletion Depths and Energy Levels
Piezoelectricity is absent in centrosymmetric crystal classes. Yet, surface acoustic wave generation and detection can be performed with high efficiency in centrosymmetrie dielectrics by deposition of interdigital metal electrodes on the dielectric surface1. In this paper we discuss results of a similar nature for volume waves. We outline a model theory for acoustic volume wave generation and detection by metal-dielectric (or metal- semiconductor) contacts deposited on centrosymmetric, cubic crystals, and present experimental verification of the main results.
