The nonlinear transport properties of weakly coupled superlattices have been investigated by measuring real-time current traces and frequency spectra. Current self-oscillations are observed for the undriven system by simply applying a dc voltage. Doped superlattices as well as photoexcited undoped s
In this work we have studied systematically the effect of fluctuations in thickness and depth of the well, as well as in the thickness of the barrier in semiconductor superlattices. Our results show that the main effect of fluctuations is to break down the whole superlattice into subsets. Localizati
Ballistic electron transport is used to study the transmittance of GaAs=GaAlAs superlattices. In a three terminal device an energy tunable electron beam is injected via a tunneling barrier into an undoped superlattice and the transmitted current is measured as a function of the injector energy. Sign
