摘要:

A quantum theory of magnetoacoustic amplification in semiconductors is given. Calculations for InSb show that the quantum theory can explain both branches of the acoustoelectric current oscillations observed by Kikuchi1and Kino.2For high electron drift velocities the gain shows a resonant behavior when the Doppler‐shifted acoustic frequency is equal to a multiple of the Larmor frequency.
