Structural and electronic characteristics of neutral and charged vacancies of cadmium and sulfur in CdS nanocrystals have been performed using the density functional method with hybrid exchange-correlation functional. Total and partial density of states, formation energies and the energies of thermodynamic transitions were calculated. Based on these theoretical findings and available experimental data, we can confirm the assumption, that the singly charged vacancies of cadmium are the centers of radiative recombination in such the structures.

“…In such cases, the tetragonal deformations are well defined. As an example of multi-beam diffraction application we have calculated fragments of multi-beam scans for heterostructures and wide-gap multi-layered II-VI compounds that are promising for the manufacture of optoelectronic devices in the green and green-yellow spectral range (Sorokin et al, 2015). Several issues arising in this research should be mentioned:…”

This article presents the results of research on multi-layered heterostructures by a modified calculation technique of multiple X-ray diffraction. The AlxIn1−xSb heterostructure and a Zn(Mn)Se/GaAs(001) multi-layered system were used as models to specify conditions for cases of coincidental coplanar three-beam or coincidental noncoplanar four-beam X-ray diffraction. These conditions provide the means for a high-precision determination of lattice parameters and strain anisotropy in layers.

“…The Cd content in these islands was found to vary from 20% to 80% [3][4][5]. The development of molecular beam epitaxy (MBE) during the last decade has led to fabrication of efficient II-VI lasers pumped optically or by electron beam, where the array of CdSe/ZnSe QDs serves as an active region [6,7]. A single-photon source operating at 220 K exploited the CdSe/ZnSe QD inserted in a nanowire to select a single excitonic line [8].…”

Density of States and Photoluminescence Spectra in the Dense Arrays of Epitaxial CdSe/ZnSe Quantum Dots with Gaussian Potential Profile

The paper reports on the studies of excitonic level arrangement in dense arrays of CdSe/ZnSe quantum dots grown by molecular beam epitaxy. Our modeling, exploiting experimental data obtained by optical and transmission electron microscopy studies, has exhibited inconsistency between the energy and width of experimental emission band and those predicted by a straightforward model for calculation of the density of excitonic states in the dots. To reach an agreement, we assume possibility of energy transfer between the adjacent dots of different sizes and propose ways for its experimental verification.
