Temperature dependence electroluminescence (EL) measurements have been performed on In(Ga)As/ GaAs quantum dot (QD) structures with varying amounts of modulation p-doping. It is found that the IEL decreases with increasing temperature with the size of reduction decreases with increasing doping lev...
