Abstract

In the present work the interband optical absorption in the ensemble of spherical quantum layers with weak quantum interaction is investigated. The distribution of layers by their inner radii is taken into account. The effect of weak electric field on the energy levels coupling and absorption character is investigated as well. It is shown that the energy spectrum 1s1p1d2s1f2p... for spherical quantum dot turns to the spectrum 1s1p1d1f2s2p... for spherical quantum layer with enough large value of inner radius. It is also shown that in spherical quantum layer, where the coupling between neighboring states is not negligible, there is no square low dependence of Stark shift on electric field strength in contrast to the rotator model.
