Properties and application of ultrasonic Lamb waves in CdxHg₁₋xTe plates

Анотація:

Group and phase velocities of the lowest orders of Lamb waves in <100>, <110> directions for (100) Cd₀.₂Hg₀.₈Te plates are calculated. Frequency dispersion of a₀ and s₀ Lamb modes velocities were measured on (111)-plates in the range of frequencies from 0.2 to 10 MHz. The frequency dependencies of relative efficiency of the Lamb modes excitation using two geometrical versions: symmetrical - with two piezoelectric transducers, and antisymmetrical - with one piezoelectric transducer, have been studied. Possible applications of studied waves including ultrasonic treatment of semiconductors have been discussed.
