Bandgap renormalization and carrier relaxation in self-organized InAs quantum dots

Strong many-body effects have been observed in time-resolved photoluminescence spectroscopy of self-organized InAs/GaAs quantum dots. Our results show that the effects generate considerable bandgap renormalization, being 28 meV at a dot occupancy of similar to 20 electron-hole pairs for the lowest t...
