Gigantic Oscillations of Dc-Voltage in Semiconductor Superlattices

Abstract

Electron properties of semiconductor superlattices (SL) in in high frequency intensive field (harmonic and biharmonic) were studied. We showed that the induced and self-induced transparency states of SL are unstable. Absolute negative conductance, unstable plasma oscillations and parametric amplificatoin of intense field harmonics destroy these states. As a result SL turns in a new state with dc-voltage and (or) non-linear plasma oscillations. The held-dependence of dc-voltage has hysteresis. The gigantic oscillations of dc-voltage arise in SL with high electron concentration. The dissipanve chaos and stochastic current oscillations occurs in a very strong field.
