STRONGLY CONFINED SEMICONDUCTOR QUANTUM DOTS - PAIR EXCITATIONS AND OPTICAL-PROPERTIES

This paper reviews a microscopic model of basic electron-hole pair exc itation processes in strongly confined semiconductor quantum dots (QD) and their influence on the optical QD properties. The effects of vale nce band mixing, Coulomb interaction, and surface polarization are tak en into account. The exciton and biexciton wave functions and energies are obtained using a numerical diagonalization method. The computed o ptical spectra, such as absorption, gain, pump-probe, and two-photon a bsorption, agree well with experiments.
