Journal of Metastable and Nanocrystalline Materials Vol. 27
In the monograph the theory of artificial atom formed from spatially separated electrons and holes (hole moving in the volume of a semiconductor (dielectric) quantum dot and an electron localized on the outer spherical interface between the quantum dot and a dielectric matrix) is developed. Predicted a new hydrogen - artificial atom, which is similar to the new alkali - metal atom. This review discusses the current state of research of artificial atoms (quasiatomic nanoheterostructures) and more complex nanostructures based on them - synthetic quasimolecules, proposed a new model of an artificial atom, satisfactorily explaining its optical and electronic properties, as well as the prospects for the development of the new scientific field.
A theory is developed for the interaction of an electromagnetic field with one-particle quantum-confined states of charge carriers in semiconductor quantum dots. In the context of dipole approximation it is established that the gigantic optical absorption cross sections in the quasi-zero-dimensional systems make it possible to use the systems as efficient absorbing materials. The effects of the resonant interaction of light with such local electron states in presence and in absence of a homogeneous magnetic field are investigated.

Review from Ringgold Inc., ProtoView: This book outlines the state of research on artificial atoms (new quasiatomic nanoheterostructures) formed from spatially separated electrons and holes and more complex structures based on them, and a new model of an artificial atom that explains its electronic properties. It also discusses interband absorption of light and the size quantization Stark effect in quasi-zero-dimensional nanosystems, and the advantages of semiconductor quantum dots for the study and diagnostics of biological nanosystems, as well as a new method for amino acid diagnostics using semiconductor dots, discussion of the interaction of isolated quantum dots with charged amino acids, and a theory for the interaction of an electromagnetic field with one-particle quantum-defined states of charge carriers in semiconductor quantum dots, including the effects of the resonant interaction of light with local electron states in the presence and absence of a homogeneous magnetic field. It also discusses excitonic quasimolecules in nanosystems, and excitons formed from a spatially separated electron and hole in dielectric quantum dots.
