SPECTROSCOPY OF EXCITONS IN HETEROSTRUCTURES WITH QUANTUM DOTS
Abstract
The appearance of a new type of electronic excitations in heterostructures with semiconductor and dielectric quantum dots - excitons formed by spatially separated electrons and holes - was considered. In the heterostructures containing semiconductor and dielectric quantum dots, the effect of a substantial increase in the binding energy of such exciton was observed (a hole moves in the volume of a quantum dot, and an electron is localized over a spherical interface between a quantum dot and matrix) in comparison with the exciton binding energy in semiconductor and dielectric monocrystals.
