Abstract
In view of combined use of piezoelectric and semiconducting properties of indium phosphide, new surface (SAW) and surface skimming bulk waves (SSBW) are described. The properties of semi- insulating InP crystals are investigated in terms of piezoelectric coupling demonstrating that the SSBW branches may be more useful than the SAW branches. Two Rayleigh modes and one Bleustein–Gulyaev branch have been experimentally investigated in the 200–300-MHz range and good agreement between theory and experiment is reported.Keywords
