摘要
Conduction electrons in a semiconductor which is subjected to an applied electric drift field and magnetic field are excited to give rise to a weakly damped electron plasma surface wave carrying negative or positive energy depending upon the direction of the applied magnetic field. Acoustic waves traveling along the surface of an adjacent piezoelectric are resonantly amplified and coupled to the electron surface waves.
