Abstract
We have studied the evolution of the photoluminescence spectrum from a single InP quantum dot in GaInP as a function of external bias. By varying the applied bias, we can control the number of electrons in the dot, leading to characteristic changes in the photoluminescence spectrum. These results explain the puzzle of multiple broad PL spectra previously observed in this materials system. In addition to explaining the properties of InP quantum dots, our results demonstrate the potential of this system for detailed studies of few- and many-particle effects in charged artificial atoms.
