Visible Photoluminescence of Zinc Oxide Films Electrochemically Deposited on Silicon Substrates
No full textContinuous crystalline films of zinc oxide (ZnO) with thicknesses of 6-10 mu m were obtained by electrochemical deposition from aqueous zinc nitrate solutions on silicon substrates with a buffer nickel layer. X-ray diffraction measurements showed that the polycrystalline films possess a hexagonal crystal lattice with predominant (0002) orientation. The obtained ZnO films exhibit strong photoluminescence in the visible spectral range at room temperature
Electrochemical and hydrothermal deposition of ZnO on silicon: from continuous films to nanocrystals
No full textThis article presents the study of the electrochemical deposition of zinc oxide from the non-aqueous solution based on dimethyl sulfoxide and zinc chloride into the porous silicon matrix. The features of the deposition process depending on the thickness of the porous silicon layer are presented. It is shown that after deposition process the porous silicon matrix is filled with zinc oxide nanocrystals with a diameter of 10-50 nm. The electrochemically deposited zinc oxide layers on top of porous silicon are shown to have a crystalline structure. It is also shown that zinc oxide crystals formed by hydrothermal method on the surface of electrochemically deposited zinc oxide film demonstrate ultra-violet luminescence. The effect of the porous silicon layer thickness on the morphology of the zinc oxide is shown. The structures obtained demonstrated two luminescence bands peaking at the 375 and 600 nm wavelengths. Possible applications of ZnO nanostructures, porous and continuous polycrystalline ZnO films such as gas sensors, light-emitting diodes, photovoltaic devices, and nanopiezo energy generators are considered. Aspects of integration with conventional silicon technology are also discussed
Electrochemical deposition of zinc oxide on a thin nickel buffer layer on silicon substrates
No full textElectrochemical deposition of ZnO from aqueous nitrate solutions on nickel and platinum electrodes was investigated using the voltammetry technique to determine the optimal regimes in both potentiostatic and galvanostatic modes for acquiring polycrystalline ZnO films. Scanning electron microscopy, X-ray diffractometry, and X-ray microanalysis of the formed ZnO films are presented, showing a polycrystalline structure of the ZnO films with a preferable orientation in the (0 0 0 2) direction and an exact stoichiometric composition. The deposited ZnO films demonstrate a strong visible yellow-greenish photoluminescence at room temperature with a maximum at 600 um that can be referred to crystal lattice oxygen defects. The maximum of the photoluminescence excitation spectrum at 370 nm corresponds to the band gap of ZnO (3.3-3.35 eV) confirming that band-to-band excitation mechanism takes place.

No full textM. N. Srinivas, the well known sociologist is widely recognised as architect of modern Indian sociology and social anthropology. His publications have been analysed by year, domain, authorship pattern, channels of communication used. Keywords, etc. The results indicate that the papers published by him are of a nature that qualify him to be a 'role model' for the younger generations to emulate.
By the end of 1995, Srinivas had to his credit 144 papers which, included 33 broad papers in sociology and anthropology; 18 papers in social change; 28 papers in village studies; 12 papers on religion; 17 papers on caste and 36 papers of general popular interest. The periods 1958-61 and 1974-77, when Srinivas was 38-41 and 58-61 years old. were his most productive periods with highest publication activity

From the correspondence of M. P. Drahomanov: two unknown letters to M. V. Vodovozov of 1894
No full textThis publication introduces into scientific discourse little-known letters of prominent Ukrainian scholar, politician and publicist M. P. Drahomanov (1841-1895), discovered in the fond of V. I. Vernadsky in the Archive of the Russian Academy of Sciences in Moscow. Two letters written in the latest period of the life of M. P. Drahomanov, which are addressed to young economist and publicist Mykola Vasyliovych Vodovozov (1870-1896), expand the source base not only for M. P. Drahomanov’s biographers. They show his ties with Russian liberals, who later formed the core of the party of constitutional democrats. A preface to the publication contains a biography of M. V. Vodovozov, and the author makes a hypothesis on the history of an acquaintance of the correspondent and the addressee, which could be connected with M. V. Vodovozov’s brother, V. V. Vodovozov, and members of the “Shelter Fraternity”, and through them with M. P. Drahomanov. The analysis of the published letters proves that M. P. Drahomanov endeavored to widen through the “Shelter Fraternity” members his contacts with democratic circles in Russia, and also to find financial support for publishing letters of Bakunin and Struve
