Optical spectroscopy of single quantum dots at tunable positive, neutral and negative charge states
D. V. Regelman, E. Dekel, D. Gershoni +6
We report on the observation of photoluminescence from positive, neutral and negative charge states of single semiconductor quantum dots. For this purpose we designed a structure e…
Correlation versus mean-field contributions to excitons, multi-excitons, and charging energies in semiconductor quantum dots
J. Shumway, A. Franceschetti, Alex Zunger
Single-dot spectroscopy is now able to resolve the energies of excitons, multi-excitons, and charging of semiconductor quantum dots with ~<1 meV resolution. We discuss the physical…
Electronic structure of self-assembled quantum dots: comparison between density functional theory and diffusion quantum Monte Carlo
J. Shumway, L. R. C. Fonseca, J. P. Leburton +2
We have calculated the exchange, correlation, and total electronic energy of a realistic InAs self-assembled quantum dot embedded in a GaAs matrix as a function of the number of el…
