Popis: We present experimental and theoretical photocurrent spectra of a GaAs/AlGaAs superlattice under the influence of electric and magnetic fields parallel to the growth axis. In this field configurations, the charge carriers are subjected to zero-dimensional confinement. Depending on the fields, we observe a complicated interplay of Wannier-Stark and Landau levels. The experimental spectra are found to be in good agreement with numerical results.
