    Abstract : It is demonstrated that the photoluminescence (PL) spectra of single selfassembled lnAs/GaAs quantum dots (QDs) are very sensitive to excitation energy and crystal temperature, which is explained in terms of modulation of the effective diffusivity of the photogenerated carriers affecting the capture probability into theQD. This effect results in a population of the QD with excess electrons, and can be used as a simple tool to create and study charged exciton complexes. READ MORE
