Giant exciton-light coupling in large size semiconductor quantum dots

Abstract

We investigate the strength of the coupling of the electronic states with the electromagnetic field in semiconductor nanospheres, taking into account the retardation effect. We show that the coupling strength is particularly strong: the bulk properties are so enhanced that the radiative decay time can reach some 30 picoseconds for quantum dots sizes of some 30 nm.
