Abstract
A microscopic theory is presented for high-field miniband transport in a two-dimensional superlattice. The energy transfer to the lateral el ectron motion is taken into account as well as scattering on polar opt ical phonons. Oscillatory current anomalies al,pear when the optical p honon frequency is a multiple of the Bloch frequency. The current osci llations, which are due to Wannier-Stark localization, are much more p ronounced in a two-dimensional than in a three-dimensional system with a superlattice structure in one direction.
