The Formation of the Charged Exciton Complexes in Self-Assembled InAs Single Quantum Dots

Abstract

We study the low-temperature photoluminescence (PL) of the self-assembled InAs single quantum dots (QDs) using conventional mu-PL setup to detect PL from an individual QD. We demonstrate, that at certain experimental conditions, what concerns the laser excitation energy the laser power and the sample temperature several novel lines appear in the PL spectra. The lines redshifted relative to the exciton PL line are interpreted in terms of charged exciton complexes.
