Abstract: (3094 Views)
In this research, an analytical investigation has been performed on the parametric excitation of an ultrasonic wave in a piezoelectric semiconductor plasma by the application of a high-frequency electric field. In the first place, estimating the quantum features of the medium, we investigate the effects of oscillating electric field on plasma. 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.
