Abstract:

In order to extract maximum information from photoluminescence studies of quantum dots single dot studies have been performed. These studies do not suffer from fluctuations in the sizes of the dots or from variations in the environment of different quantum dots. We have performed experiments on single InPGaInP quantum dots. The spectra always reveal several emission lines no matter how much the excitation intensity is reduced. at least 4 or 5 irreducible lines are observed with an energy spacing of the order of 10 meV. The linewidth of the peaks is about 2 meV which is much larger than ksub-BT at the experimental temperature of T 5 K.
