Initial relaxation of photoexcited carriers in GaAs and GaAs quantum wells under subpicosecond excitation
(Pergamon Press, 1988)
After excitation by a subpicosecond pulse, we observe a very slow rise of the luminescence both in GaAs and in GaAs quantum wells. By comparing the results in GaAs and InP, we show that the slow rise in GaAs and GaAs quantum ...
