Evidence for excitonic polarons in InAs/GaAs quantum dots

We investigate the interband transitions in several ensembles of self-assembled InAs/GaAs quantum dots by using photoluminescence excitation spectroscopy under strong magnetic field. Well defined resonances are observed in the spectra. A strong anticrossing between two transitions is observed in all...
