Multiexciton Spectroscopy of a Single Self-Assembled Quantum Dot
Multiexciton Spectroscopy of a Single Self-Assembled Quantum Dot
We apply low temperature confocal optical microscopy to spatially resolve, and spectroscopically study a single self assembled quantum dot. By comparing the emission spectra obtained at various excitation levels to a theoretical many body model, we show that: Single exciton radiative recombination is very weak. Sharp spectral lines are due …
