Abstract

Within the framework of adiabatic approximation the energy levels and direct interband light absorption in strongly oblate semiellipsoidal quantum dot's ensemble are studied. Analytical expressions for the particle energy spectrum and absorption threshold frequency in the regime of strong size quantization are obtained. Selection rules for quantum transitions are revealed. To facilitate the comparison of obtained results with the probable experimental data, the small semiaxe size dispersion distribution of quantum dots growing by two experimentally realizing distribution functions have been taken into account. Distribution functions of Lifshits-Slezov and Gaussian have been considered.
