Abstract

The phenomenon of acoustoelectric effect is similar to that of self focusing of an optical beam. A phenomenological approach has been used to determine the change in collision frequency, which is greater than change in electron mass for all acoustic wave frequencies and temperatures. It has been shown that both change in collision frequency and electron mass both increase rapidly and then increase slowly and show saturation at high frequency. It is also shown that at the low temperature, the frequency for saturation and mass with respect to the carrier concentration was found to be very small.
