We investigate the dephasing dynamics in semiconductor superlattices using timeresolved four-wave mixing. The signals show a periodic modulation which can be related to Bloch oscillations in the superlattice miniband. The oscillation frequency is strongly dependent on the applied field, in agreement
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
