Abstract :
We experimentally investigated electric field domain formation in a semiconductor structure that consists of multiple finite GaAs/AlGaAs superlattices separated with thick barriers. From the measurements of conductance oscillation and transition of the photoluminescence spectra associated with the Wannier-Stark localization, we studied the behavior of an electric field concentrated into the thick barrier and the superlattice regions
