Investigation of the features of electronic spectrum of quantum dots in narrow-gap semiconductors

Samples with quantum dots (QDs) of narrow-gap semiconductors of the A$_3$B$_5$ group (indium antimonide) and the A$_2$B$_6$ group (mercury selenide) have been studied. The absorption spectra of the investigated QDs are analyzed and the correspondence of the maxima in the spectral characteristics to the model representations of the calculated electronic energy spectrum for this materials is assessed. It is concluded that used model representations requires refinement, primarily due to the fact that studied objects are nanocrystals with complex geometry.
