Charged excitons in individual quantum dots: effects of vertical electric fields and optical pump power
We investigate the influence of optical pump power on a series of charging events of individual quantum dots embedded in a field effect structure. Increasing the optical pump powers moves all charging events towards more negative voltages and charged biexciton states in addition to single exciton st...
