Abstract:

For the regime of strong quantization the interband transitions in narrow-gap InSb cylindrical quantum dots are theoretically investigated in the presence of homogeneous magnetic field. In the frame of two-band Kane model for electrons (light holes) and parabolic dispersion for heavy holes, the absorption coefficients of non-interacting quantum dot ensemble are calculated. The absorption threshold frequencies are defined. It is shown that these frequencies correspond to infrared range. The influence of Coulomb interaction between electron and hole on the energetic spectrum of the mentioned system is discussed in framework of perturbation theory. Quantitative calculations are performed using the recent experimental data on the growth of InSb quantum dots.
