Abstract

Acoustoelectric effect in semiconductor superlattice (SL) in the region ql >>1 has been studied. The equation of motion of the lattice has been transformed into a simple form which becomes identical with the dynamic equation for the wave amplitude in the theory of plasma turbulence. A dispersion relation has been derived from the acoustoelectric current J on the constant electric field E. It is noted that when the electric field is negative the current J rises, reaches a peak and falls off. On the other hand, when the electric field is positive the current decreases, reaches a peak and then rises. A similar observation has been noted for an acoustoelectric interaction in a multilayered structure resulting from the analysis of the Si/SiO2 structure.
