Abstract
We report a spectroscopic investigation of the stationary and transient recombination processes in rectangular GaAs quantum well-wires. The ground level exciton states are studied by linear and non linear photoluminescence excitation spectroscopy, providing information on the one-dimensional exciton binding energy and on the actual band gap edge of the wires. The carrier density dependence and the temporal evolution of the band gap renormalization in GaAs quantum wires have been determined by a line-shape analysis of the time resolved electron-hole plasma luminescence. The obtained data are compared with recent theoretical calculations.
