Charged excitons in individual quantum dots: effects of vertical electric fields and optical pump power

Abstract:
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 states are observed. The linear shift in voltage with pump power is explained by the accumulation of photogenerated holes within the structure. © 2002 Elsevier Science B.V. All rights reserved.
