Abstract: | . In Ihe went work we have ansidered a parameVc intenction in a piezoelectric semimnduaor plasma. The three waves involved in the parametric excitation are the pump wave, a coupled upper hybrid-xoustic wave and an extraordinary wave. An analytical expression for the gmMh of the unslable mode is derived and an expression for the threshold electric field for the onset of the instability is also derived. We have numerically investigdted the dependence of the tbshold electric field for different values of the background parameters for a typical piezoelectric semiconductor OnSb) and have given a numerical estimation of the growth rate. |
