Abstract
Trajectories of charge carriers for a one-dimensional superlattice under the action of high-frequency electromagnetic fields are obtained by an approximate method, which is a generalization of Kapitsa’s scheme. It is shown that the existence of high-frequency fields leads to qualitative changes of both the miniband shape and particle motion. The possibility of a smooth changing of superlattice parameters by an external field amplitude is demonstrated. We present a number of low-frequency dynamic, thermodynamic, and kinetic manifestations of the phenomena in such a specific system.
