Abstract

The authors have introduced a technique to investigate the carrier dynamics of semiconductor nanostructures. Such a technique is based on the measurement of time-resolved differential photoluminescence spectra induced by subpicosecond pump and probe laser pulses by adjusting the temporal delay between them. Their results obtained on the InAs quantum dots embedded in InGaAsGaAs quantum wells using such a technique indicate that the exciton decay time, integrated photoluminescence intensity, and photoluminescence linewidth exhibit unique dependences on temperature.
