ACOUSTOELECTRIC INTERACTION IN p-InSb AT LOW TEMPERATURE

Abstract
We have measured the ultrasonic attenuation in p-InSb in the range 1 - 20 K in the 30 - 600 MHz frequency range under magnetic fields up to 7T, concurrently with magnetoresistance measurements. Both the relaxation peak observed near 10 K and the low temperature field dependence are governed by the piezoelectric interaction and both effects are in good agreement with the acoustoelectric theory of Hutson and White.
