Abstract

A p-type semiconductor barrier layer is provided in the vicinity of undoped quantum dots, and holes in the p-type semiconductor barrier layer are injected in advance in the ground level of the valence band of the quantum dots. Lowering the threshold electron density of conduction electrons in the ground level of the conduction band of quantum dots in this way accelerates the relaxation process of electrons from an excited level to the ground level in the conduction band.
