✦ Synopsis

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

We have investigated the influence of the final states of bound-to-continuum transitions within the conduction band of asymmetric quantum well structures on the photocurrent. This influence manifests itself by an energy-dependent oscillation of the current direction. We observe pronounced oscillatio
