Abstract

A study was performed on level degeneracy and temperature-dependent carrier distributions in self-organized In_0.4Ga_0.6As quantum dots. The femtosecond three-pulse pump-probe spectroscopy was used to investigate the transparency conditions. It was found that the temperature-dependent behavior of the transparency condition was consistent with calculations using a multilevel model with a large density of states in the quantum-well reservoir.
