| Abstract(in English) | Carrier transport in short-period superlattices is experimentally studied using time-resolved photoluminescence,time- resolved photocurrent and photocurrent spectra under high optical input intensities.Observed rapid collapse of Wannier-Stark localization indicates electric field screening by photo-generated space charges with a positive feedback process near blue-shifted absorption band-edge.Pile-up of carriers beside clad layers of superlattice is clearly explained with the Fowler-Nordheim tunneling scheme.In addition,a temporally delayed photoluminescence from the end of superlattice region indicates the carrier transit time in superlattice and a reverse injection of electron due to an inverse screening field mainly created by holes through effective-mass filtering. |
