The article is devoted to the determination of the status of precedent units (precedent names and expressions) in the system of intertextual means of contemporary Ukrainian media discourse. There was analyzed the phenomenon of intertextuality in the broad and narrow senses; the functions of precedent units that realize the main media discourse purpose of informing and influence were revealed. The...
Method of formation of regular PAA without a barrier layer in the process of anodizing of Al-film on n-type Si has been developed. Semiconductor InGaN-structures were selectively grown in modified PAA-template by MO VPE. Formed self-organized nanostructures InGaN have nonpolar crystallographic α-orientation. Investigations of luminescent properties and analysis of the spectral characteristics have...
At present carbon nanotubes (CNT) are the most prospective cathode material for triode applications because of their strong field emission (FE) at low electric fields. The FE homogeneity of flat CNT cathodes, however, is still limited by their rather fast and uncontrolled growth which usually leads to strongly varying field enhancement and current carrying capability of the individual emitters. Therefore,...
Metallic nanostructures with controllable dimension and high aspect ratio provide an interesting alternative to carbon nanotubes for triode applications which require highly efficient and homogeneous field emission cathodes. Noble metal nanowires (NW) were electrochemically synthesized into the randomly distributed cylindrical pores of polycarbonate templates fabricated by GeV-ion irradiation, selective...
Direct electron optical study has been carried out for anodic film grown on substrates comprising an aluminium layer superimposed on nickel (Ni-Al bilayer) in 0.05M oxalic acid electrolyte. The latter was expected to provide the conditions for thorough barrier layer dissolution at the nickel/alumina interface in order to produce nanoporous templates suitable for Ni electrochemical deposition and forming...
