Acousto-electric effect

Acousto-electric effect is a nonlinear phenomenon of generation of electric current in a piezo-electric semiconductor by a propagating acoustic wave. The generated electric current is proportional to the intensity of the acoustic wave and to the value of its electron-induced attenuation. The effect was theoretically predicted in 1953 by Parmenter. Its first experimental observation was reported in 1957 by Weinreich and White.
