Abstract

The theory of excitonic quasimolecules (formed of spatially separated electrons and holes) in nanosystems that consist of semiconductor quantum dots synthesized in a borosilicate glass matrix is presented. It is shown that exciton quasimolecule formation is of the threshold character and possible in nanosystem, if the spacing between the quantum dot surfaces is larger than a certain critical spacing. It was found that the binding energy of singlet ground state of exciton quasimolecule, consisting of two semiconductor quantum dots, is a significant large value, larger than the binding energy of the biexciton in a semiconductor single crystal by almost two orders of magnitude.
