Effect of weak positional disorder on the miniband structure of spherical quantum dot chains
R. Ya. Leshko
A theoretical framework is developed for the electron miniband structure in one-dimensional chains of spherical quantum dots subjected to weak positional disorder. Within the tight…
Electron and hole energy spectrum of non-concentric spherical core-shell quantum dot under an externally applied electric field
R. Ya. Leshko, I. V. Bilynskyi, O. V. Leshko +2
A model of the non-concentric spherical core-shell quantum dot under the influence of an externally applied electric field was proposed. It was established that the energy spectrum…
Electron energy spectrum of the spherical GaAs/AlGaAs quantum dot with several impurities on the surface
R. Ya. Leshko, I. V. Bilynskyi, O. V. Leshko +1
The model of a spherical quantum dot with several donor impurities on its surface is suggested. The electron energy spectra are studied as a function of the quantum dot radius and…

I. V. Bilynskyi, V. B. Hols'kyi, R. Ya. Leshko
The quantum molecule consisting of three quantum dots that forms a triangle with its centers is studied. The electron wave function in the nanosystem is written using the linear co…
Analysis of the effect of polarization traps and shallow impurities on the interlevel light absorption of quantum dots
V. I. Boichuk, R. Ya. Leshko, D. S. Karpyn
A spherical quantum dot (QD) heterosystem CdS/SiO has been studied. Each QD has a hydrogen-like impurity in its center. Besides that, it has been accounted that a polarization…
Interlevel absorption of electromagnetic waves by nanocrystal with divalent impurity
V. I Boichuk, R. Ya. Leshko
The energy spectrum of central divalent impurity is calculated using the effective mass approximation in a spherical quantum dot (QD). The dipole moment and oscillator strength of…
