MAGNETO-ACOUSTIC AMPLIFICATION IN INSB,
Abstract
A quantum theory of magneto-acoustic amplification in semiconductors is given. Calculations for InSb show that the quantum theory can explain both branches of the acousto-electric current oscillations observed by Kikuchi and Kino. For high electron drift velocities the gain shows a resonant behaviour when the Doppler-shifted acoustic frequency is equal to a multiple of the Larmor frequency. (Author)
