抄録

Exciton in isolated InxGa1-xAs quantum disk was studied by probing single-dot photoluminescence. Each of the excitonic emission was found to be excited via a number of sharp-excited state resonances, thereby the discrete density of state and long-lived phase coherence of the states were proven. A significant contribution of the biexciton excitation was found to enable two-photon absorption, making optical excitation process complex. It leads to a dynamic quantum mechanical interference in the excitation via exciton/biexciton states.
