Correlated Photon-Pair Emission from a Charged Single Quantum Dot
arXiv:cond-mat/0407441 · doi:10.1103/PhysRevB.71.235328
Abstract
The optical creation and recombination of charged biexciton and trion complexes in an (In,Ga)As/GaAs quantum dot is investigated by micro-photoluminescence spectroscopy. Photon cross-correlation measurements demonstrate the temporally correlated decay of charged biexciton and trion states. Our calculations provide strong evidence for radiative decay from the excited trion state which allows for a deeper insight into the spin configurations and their dynamics in these systems.
