Abstract
The features of high-frequency currents in superlattices lacking a center of symmetry are established theoretically. It is assumed that the asymmetry shows up in intraband electron-scattering processes. Self-induced transparency is found to be possible. In a high-frequency field the current has a dc component with a nonmonotonic dependence on the field amplitude.
