Abstract

We present a comparative study on the quantum size effects in CdS and CdSe spherical dots, using first-principles derived semi-empirical pseudopotential method. Various properties including single-particle energy levels, characterization of individual electron wave functions, interband and intraband transitions, electron-hole Coulomb and exchange interactions, and excitonic band gap are investigated. The similarity and difference between CdSe and CdS dots are discussed. Our specific findings are rather lengthy, and are summarized in Section IV.
