All-inorganic perovskite CsPbBr3 and Cs4PbBr6 nanoparticles are being intensively studied due to their unique properties and wide range of applications; however, however, the nature of their optical properties is not yet fully understood due to the difficulty of synthesis of singlephase nanoparticles. In this article we describe the features of the synthesis of single-phase particles ...

Currently, ABX3 nanoparticles (NPs) based on lead halides attract the attention due to their unique optical properties and a wide range of applications. The preparation of NPs with lead as a partial or complete replacement is particularly interesting because of the toxicity of this chemical element and most of its compounds. In this study, we propose a ...

GaN nanowires were grown using selective area plasma-assisted molecular beam epitaxy on SiOx/Si(111) substrates patterned with microsphere lithography. For the first time, the temperature–Ga/N2 flux ratio map was established for selective area epitaxy of GaN nanowires. It is shown that the growth selectivity for GaN nanowires without any parasitic growth on a silica mask can ...

The preparation of new hybrid halobismuthates [Py2(XK)]2[Bi2Br10], [Py2(XK)]2[Bi2I10], and the [Py2(XK)](I3)2 polyiodide ([Py2(XK)]2+ = 1,1′-(1,4-phenylenebis(methylene))bis(1-pyridinium)) is reported. The significant deviation of unit cell parameters from Vegard's law in a series of solid solutions [Py2(XK)]2[Bi2Br10−xIx] is shown. The specifics of halogen atom substitution was discussed based on the site occupancy study derived from powder X-ray diffraction data. The ...

Absorption, emission and excitation spectra of 50 MeV electron beam irradiated and asgrown YAG single crystals were studied and compared in the 10-300 K temperature range using timeresolved luminescence spectroscopy under UV/VUV/XUV excitation by synchrotron radiation and cathodoluminescence. The emission spectra consist of intrinsic (excitonic) and defect related nonelementary bands in the VIS/UV range. It ...

Abstract: Polymer dielectrics subjected to intense radiation fluxes exhibit a radiation-induced
conductivity (RIC). Polyimide is a good dielectric with excellent mechanical and thermal properties
featuring high radiation resistance currently widely used in the spacecraft industry. Its RIC has
been extensively studied in several laboratories. The purpose of the present study is to make a
direct measurement of the RIC ...

Abstract: Electrical properties of the thin films of poly(arylene ether ketone) copolymers (co-PAEKs)
with the fraction of phthalide-containing units of 3, 5 and 50 mol% in the main chain were
investigated by using radiation induced conductivity (RIC) measurements. Transient current
signals and current-voltage (I-V) characteristics were obtained under exposing 20÷25 thick films of
the co-PAEKs to monoenergetic electron pulses ...

Работы посвящена исследованию влияния электронного облучения на параметры полупроводниковых диодов при прохождении одиночного импульса тока. Приведены результаты расчетов и экспериментальных исследований влияния электронного облучения на импульсную электрическую прочность. Показано, что при увеличении длительности импульса уменьшение величины амплитуды импульса тока, необходимого для достижения критической температуры, происходит за счет увеличения теплового сопротивления. ...

The change in the charge state of metal–insulator–semiconductor (MIS) structures with a twolayer silicon-dioxide–phosphosilicate-glass gate insulator upon their modification under electron irradiation and high-field electron injection is studied. A thin glass film is formed by doping a thermal SiO2 film formed on the surface of a silicon wafer with phosphorus. It is found that the ...
