AbstractA decrease in the longitudinal-transverse exciton splitting in a wide GaAs/AlGaAs quantum well (QW) in a homogeneous electric field has been theoretically considered. The dependences of the splitting on the applied field have been determined. The exciton reflection spectra of the wide QW have been calculated for the case where the field is ...

The results of the spectral studies of molten mixtures xNa2O–Re2O3–(100–x)B2O3 (Re = Pr, Nd; x = 0–50) at 1273 K are reported. In both the mixtures, the cyclical changes in the coordination numbers of boron atoms, for which the limits of the concentration variation of fourfold coordinated boron groups are specified, are observed with an increase in...

The radiation hardness of three types of BaTiZrO3 coatings obtained by synthesis from the powder mixtures BaTiO3 + ZrO3, BaCO3 + TiO2 + ZrO3 (micron size), and BaCO3 + TiO2 + ZrO3 (nanopowder) deposited by the detonation method on metal substrates is investigated. The high radiation resistance of all types of coatings to the action of electrons wit...

Developed are projects of State Standards of Ukraine referring to determination of bromide, iodide, and nitrate ions in waters of different types. The method of determination of bromide,ions is based on registration of reflection spectra of products of bromination of phenol red, iodide ions—on the oxidation of the latter to iodine, its gas extracti...

A new contactless nondestructive technique for determining the free carrier density in single-crystal samples of CdxHg1–xTe solid solutions and multilayer epitaxial heterostructures based on them from farinfrared reflection spectra is proposed. The characteristic point and corresponding wavenumber in the room-temperature spectral dependence of the ...

Modification of the surface layers of polyimide films under γ-radiation and implantation with 30–100 keV Ni, Mn, Ag, Co, Fe and B ions in the dose range of 1015–1.5 × 1017 cm–2 are investigated by reflection spectra measurements. Ion implantation is shown to lead to the modification of reflection from the rear (unimplanted) polymer side. Depending ...
