Abstract
A detailed analysis of phonon-assisted absorption processes in a single InGaAs quantum dot was performed by multichannel photoluminescence excitation spectroscopy as a function of magnetic field. GaAs LO phonon-assisted generation of exciton and biexciton states was observed at high excitation powers. Magnetic field-induced detuning of the resonance conditions resulted in a two-fold diagonal splitting of the exciton and a symmetric four-fold splitting of the biexciton resonances.
