Abstract

We have computed the light-current characteristics of an ensemble of 10 6 quantum dots with localised Shockley-Read-Hall (SRH), radiative and Auger recombination between states with integer occupancy. The radiative, non-radiative via defects and Auger recombination rates have similar dependences on electron number and hence there is no transition from one dominant process to another as the injection is increased. The light-current characteristics of the dot system alone are similar for non-charge-neutral and neutral dots even though the individual recombination rates have very different dependences on electron number.
