В. Аннотация: Методами растровой электронной микроскопии, рентгенофазового и рентгеноспектрального анализа, оже-спектроскопии изучались изменения структуры, фазового и элементного состава имплантированных ионами В+ (Е = 80 кэВ, Ф = 1·10 16 ион/см2) пленок Cu-C 60 -Cu после термического отжига в вакууме. Установлено, что термический отжиг имплантированнных пленок приводит к рекристаллизации фуллеритовой фазы и образованию новой фазы Cu x C 60 в виде наностержней. Доп. сведения: Секция 4.

N.; Vlasukova, L. A.; Komarov, F. F.; Makhavikou, M.; Milchanin, O. V.; Wendler, E.; Ronning, C.; Zaph, M.; Korolev, D. S. Аннотация: Samples of SiO2 (600 nm)/Si have been implanted with Zn ions (140 keV, 5×10 16 cm-2) and O ions (50 keV, 5×10 16 cm-2) at room temperature and afterwards annealed at 750ºС for 120 min in air ambient. The Zn depth distribution profiles of the implanted and annealed samples were analyzed by Rutherford backscattering spectroscopy (RBS). The structural and light emitting properties of the annealed samples were studied using TEM in “plan-view” geometry as well as electron micro-diffraction and photoluminescence (PL) at low (4 K) and room temperatures. The RBS analysis has revealed the bimodal shape of the Zn concentration profile. TEM analysis shows a non-uniform Zn-based cluster size distribution after annealing. The near-surface (0-60 nm) layer contains small clusters (2-11 nm). The large clusters (up to 35 nm) and clusters covered with oxide shells as well as and the secondary defects have been formed in the depth of 60-120 nm. The deepest implanted layer (120 - 200 nm) layer contains small nanoclusters with sizes of 5-10 nm. The crystal structure of the synthesized ZnO clusters is confirmed by the presence of narrow rings in diffraction patterns. Room-temperature PL spectrum exhibits the intensive deep level emission (DLE) in visible spectral range with dominant orange band (2.1 eV) and sharp weak near band edge (NBE) emission at 3.244 eV. At low-temperature (4.2 K) UV band dominates in PL spectrum which consists of two intense peaks at 3.324 and 3.274 eV and some narrow bands in blue-violet range attributed to phonon replicas of these bands. The crucial role of oxygen interstitials in radiative recombination is discussed. Доп. сведения: Секция 4. Формирование наноматериалов и наноструктур = Section 4.

K. Аннотация: The paper presents the results of a study of the effect of the difference in the applied potentials on the structural properties and phase composition of thin CdSe films obtained by the method of electrochemical synthesis. It has been established that a change in the difference of the applied potentials leads to a change in the morphology of the thin films obtained, as well as a reorganization of the phase composition, which can later be used in the practical application of these films.

K. Аннотация: The paper presents the results of a study of the effect of irradiation with heavy xenon ions on the structural properties of CoZ-nO-based nanostructures. The dependences of the change in the phase composition as a result of irradiation are obtained; critical irradiation doses are established at which nanostructures undergo partial destruction.
