Annotation

The conditions for ultrasound generation in a CdS crystal have been studied. The vibration equation in the piezoelectric semiconductor with specified boundary conditions is solved by the Bubnov - Galerkin method. Expressions are found for the critical electron drift velocity Vocr and the ultrasonic frequency ω_cr corresponding to the beginning of generation. The results are compared with previous results.
