WebbIt is shown that carrier capture is essentially unaﬀected whereas the intradot relaxation mechanisms, at least at low carrier concentrations, are fundamentally diﬀerent. The phonon mediated cascade relaxation found in the undoped reference sample is replaced by eﬃcient scattering with the built-in carriers in the case of the doped structures. WebbFor majority carriers, the equilibrium carrier concentration is equal to the intrinsic carrier concentration plus the number of free carriers added by doping the semiconductor. Under most conditions, the doping of the semiconductor is several orders of magnitude greater than the intrinsic carrier concentration, such that the number of majority ...
