Abstract. We have found the effect of significant (almost two orders of magnitude, when compared with the binding energy of biexcitons available in CdS single crystals) increase in the binding energy of the singlet ground state of the excitonic quasimolecule consisting of two CdS quantum dots.

Keywords: spatially separated electron and holes, quantum dots, binding energy, Coulomb and exchange interactions

Анотація. Виявлено явище значного (майже на два порядки величини) зростання енергії зв’язку основного синглетного стану екситонної квазімолекули, яка складається з двох квантових точок CdS, порівняно з енергією зв’язку біекситона в монокристалах CdS.
