Abstract
Effects of a periodic external signal on collective dynamics of charge in semiconductor superlattices have been studied. It has been shown that an external electric field is able to synchronize the transport of domains of high charge density, and thus electrical current through the superlattice. The synchronization phenomena are accompanied by the sharp increase of absorption on the frequency of external field, and manifest themselves in modification of current-voltage characteristics.
