INTERACTION OF MILLIMETER AND SUBMILLIMETER WAVE FIELDS WITH MINIBAND ELECTRONS IN A SEMICONDUCTOR SUPERLATTICE

摘要

We present experimental results showing that the irradiation of a doped short-period GaAs/AlAs superlattice leads to a reduction of the conductance either due to rectification (for fields at frequencies below 1 THz) or due to dynamical localization of the miniband electrons (for fields above 1 THz).
