A theoretical study of exciton confinement in small CdS and ZnS quantum dots is reported. In
our calculational scheme the hole is described by an effective bond-orbital model that …

A simple variational calculation is presented for the ground-state energy of an electron-hole
system confined in a microcrystal with finite potential barriers. It is shown that the effect of the …

The optical properties of silicate glasses under high-power, 850-nm femtosecond laser
irradiation have been studied. Photoinduced processes occurred at irradiances well below …

We consider a new type of nonradiative transitions in nonmetallic solids. The transitions are
not accompanied by heat release but by large (compared with interatomic distances) …

A finite-depth square-well model is used to show that the band gap of a nanoparticle for a
given size can be tuned by embedding the nanoparticle in different matrices. This may find a …

An effective mass approximation (EMA) with finite-depth square-well potential is used to
investigate the size-dependent band gap (BG) of PbS and CuBr nanoparticles embedded in …

После создания основ квантовой теории твердых тел на протяжении многих
десятилетий развития физики полупроводников и диэлектриков считалось …

Existing Petawatt class lasers today based on Nd: glass architectures operating at nominally
500 J, 0.5 ps use meter-scale aperture, gold-overcoated master photoresist gratings to …

This paper reports on the effects of gamma ray irradiation on various properties of the
nuclear waste glass simulant known as International Simple Glass (ISG). The study was …

Absorption spectra of a number of 13Na2O–10CaO–6MgO–71SiO2 glass samples doped
with iron were studied in the spectral range 3000–200 nm (3300–50 000 cm− 1). The …
