Abstract:

A theory is developed for a superatom composed of a spatially separated electron and hole. The electron in this case is localized above a spherical interface. The hole moves in the volume of a semiconductor quantum dot (a quantum-dot–dielectric matrix). An effect is detected consisting of a substantial increase (by a factor of 4.1–72.6) of the binding energy of a superatom containing a cadmium sulfide quantum dot by comparison with the binding energy of an exciton in single-crystal CdS. The possibility is discussed of experimentally studying superatoms and their role in various regions of physical phenomena.

Keywords:

superatom, quasi-zero-dimensional nanosystems, quantum dots, spatially separated electron and hole
