Abstract

The carrier density dependence and the temporal evolution of the ground level parameters of a quasi-one-dimensional electron-hole plasma confined in GaAs quantum wires have been studied by a line-shape analysis of the time-resolved luminescence. The obtained data are compared with the available theoretical calculations.
