Abstract

In the work we investigated the influence of the dimensional quantization on the probability of optical transitions with no k-selection rule. It is shown that calculations of the recombination rate and gain coefficient will be inaccurate if they are performed with using the probability of optical transitions determined for bulk semiconductors. Successive examination of radiative transitions with no the k-selection rule leads to a qualitative coincidence of the dependence of the spontaneous recombination rate on the quantum well width with the results obtained in the model of direct transitions.With the suppression of the constant injection efficiency the inversion current value is practically independent of the quantum-well layer thickness. Various approaches for the calculation of the spontaneous recombination rate are discussed.
