Characterization of ZnSe nanocrystals grown by vapor phase epitaxy

Tishchenko, V.V.; Kovalenko, A.V. (Физика низких температур, 2006)

This paper reports the application of scanning electron microscopy, x-ray diffraction, and photoluminescence techniques for characterization of ZnSe nanocrystals grown on GaAs (100) substrate from the vapor phase. The ...
Individual glow bands of Mn²⁺ ions photoluminescence in plastically deformed ZnS single crystals

Prokofiev, T.A.; Kovalenko, A.V.; Polezaev, B.A.; Bulanyi, M.F.; Gorban, A.A.; Hmelenko, O.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)

The spectra of a photoluminescence (PL) in plastically deformed (PD) ZnS:Mn single crystals are investigated. It is shown that the PD processes cause change of a quantitative ratio between separate types of glow manganese ...
Photoluminescence of ZnSe nanocrystals at high excitation level

Tishchenko, V.V.; Kovalenko, A.V. (Физика низких температур, 2009)

The excitation-dependent photoluminescence (PL) of ZnSe nanocrystals (NC) grown on GaAs (100) substrate was studied. The PL spectra observed corroborate previous observations of a bimodal size distribution of NC grown, ...
Preparation of zinc oxide nanopowders doped with manganese, which have ferromagnetic properties at room temperature

Vorovsky, V.Yu.; Kovalenko, A.V.; Kushneryov, A.I.; Khmelenko, O.V. (Functional Materials, 2018)

The paper analyzes magnetic properties, crystal structure and EPR spectra of ZnO:Mn nanocrystals obtained by ultrasonic spray pyrolysis. It has been investigated influence of the type of carrier gas - air and nitrogen on ...
Simultaneous observations of the Moon at λ = 6.2 cm using 22-m radio telescopes at Pushchino and Simeiz during Leonid meteor shower in November 2001

Volvach, A.E.; Berezhnoy, A.A.; Khavroshkin, O.B.; Kovalenko, A.V.; Smirnov, G.T. (Кинематика и физика небесных тел, 2005)
The lunar radio flux during Leonid meteor showers and lunar eclipse

Volvach, A.E.; Berezhnoy, A.A.; Khavroshkin, O.B.; Kovalenko, A.V.; Smirnov, G.T. (Кинематика и физика небесных тел, 2005)

Significance variations of lunar radio flux at the wavelength of 2.46 cm were detected in Irbene (Latvia) during the maxima of Leonid shower on the Moon in 2000 and 2001. These results were interpreted as detection of lunar ...
The peculiarities of the properties of ZnSxSe₁-x nanocrystals obtained by self-propagating high-temperature synthesis

Kovalenko, A.V.; Plakhtii, Ye.G.; Khmelenko, O.V. (Functional Materials, 2018)

ZnSxSe₁-x nanocrystals of all compounds were obtained by self-propagating high-temperature synthesis. It was found that the obtained samples had dimensions of 55±5 nm and were characterized by a mixed crystalline structure. ...
