Abstract
Abstract- In this research, an analytical investigation has been performed on instability and excitation of ultrasonic waves in a semiconductor medium by the application of a high-frequency electric field. To this end, using a set of basic hydrodynamic equations including quantum corrections, dispersion relations of the ultrasonic waves in the presence of electric field calculated and the possibility of waves instability in the quantum regime is investigated. The results show that the high- frequency electric field, near the electron-plasma frequency, produces a nonlinear coupling between the ultrasonic waves and electron-plasma waves and leads to an instability which can be increased by quantum effects.
