Abstract
Many-body phenomena related to electron-hole plasmas or liquids in typ e-II GaAs/AlAs superlattices grown in (100) and (311) direction are in vestigated by time-resolved luminescence. The band-gap-renormalization in a (100) superlattice is determined using a luminescence lineshape fit, revealing the influence of the space-charge effect on the type-II transition. The dynamics of the liquid phase which is only present in the (311) quantum-well-wire is studied.
