We present selective photoluminescence and photoluminescence excitation spectroscopy on self-assembled quantum dots. These spectroscopic techniques reveal a large apparent 'Stokes' shift in In(Ga)As-Ga(Al)As self-assembled quantum dots. We demonstrate that the first two excited states observed in PL
We have studied the interband excitations of an ensemble of InAs self-assembled quantum dots by detecting absorption directly in transmission experiments. The dots are embedded in a MISFET structure, allowing the dots' electron occupation to be controlled with a gate voltage. We show how Coulomb blo
