Effect of nitrogen ion irradiation parameters on properties of nitrogen-containing carbon coatings prepared by pulsed vacuum arc deposition method
Studies of the effect of nitrogen ion irradiation on the structure and properties of nitrogenated amorphous carbon coatings prepared on polished sitall and silicon substrates by the pulsed vacuum arc deposition method are presented. The techniques used in the investigations were electron energy loss spectroscopy, Raman spectroscopy, and atomic force microscop
Nanostructured coatings based on amorphous carbon and gold nanoparticles obtained by the pulsed vacuum-arc method
Nanostructured coatings based on diamond-like carbon and gold-doped carbon with a thickness of 100-300 nm were obtained by a pulsed vacuum-arc method on silicon substrates. The structure of the coatingswas studied by high-resolution transmission electron microscopy, the elemental composition was studied by X-ray microanalysi
The effect of vacuum annealing on the structure and properties of the electrically conductive a-CN coating
Electrically conductive amorphous carbon nitride (a-CN) coatings were deposited onto various substrates by pulsed vacuum-arc sputtering of a graphite cathode with simultaneous irradiation of the substrate with nitrogen ions. Deposition temperature was less than 60 ◦C. We investigated the effect of vacuum annealing at a temperature of 600◦С on the elemental composition, structure, electrical and optical properties of the obtained films. It was found that the elemental composition of the coating practically does not change over the thickness of the coating after annealing, while the remaining characteristics change significantl
Influence of formation conditions, subsequent annealing and ion irradiation on the properties of nanostructured coatings based on amorphous carbon with gold, silver and nitrogen additives
Nanostructured coatings based on amorphous carbon and carbon-doped with gold, silver, and nitrogen were obtained by the pulsed vacuum-arc method. Carbon coatings have been annealed in a vacuum as well as treated with argon ion
The local crystallization in nanoscale diamond-like carbon films during annealing
The local crystallization during annealing at 600° C in nanoscale diamond-like carbon coatings films grown by pulsed vacuum-arc deposition method was observed using modern techniques of high-resolution transmission electron microscopy. The crystallites formed by annealing have a face-centred cubic crystal structure and grow in the direction [011] as a normal to the film surface. The number and size of the crystallites depend on the initial values of the intrinsic stresses before annealing, which in turn depend on the conditions of film growth. The sizes of crystallites are 10 nm for films with initial compressive stresses of 3 GPa and 17 nm for films with initial compres- sive stresses of 12 GPa. Areas of local crystallization arising during annealing have a structure dif- ferent from the graphit
Properties of carbon coatings obtained by pulsed high power methods of vacuum-arc and magnetron sputtering
Investigation results of the structure, mechanical, tribological and adhesion characteristics of carbon coatings obtained by two different methods: high-power impulse magnetron sputtering and pulsed cathodic arc deposition are presente
Strengthened Lindblad inequality: applications in non equilibrium thermodynamics and quantum information theory
A strengthened Lindblad inequality has been proved. We have applied this
result for proving a generalized -theorem in non equilibrium thermodynamics.
Information processing also can be considered as some thermodynamic process.
From this point of view we have proved a strengthened data processing
inequality in quantum information theory.Comment: 7 pages, revte
Far-infrared and radio emission features of the galactic nuclear region
In this paper the results of the Galactic nuclear region study in far-infrared and radio-wave bands are presented. Image processing methods are used for SkyView and IRSA archive images. On the basis of image synthesis, image analysis, and isophots the structure of the Galactic nuclear gas-dust disk and its borders are determined. Brightness temperature distribu-tions for gas and dust components of the disk and their average values (Ть8"3-! К, TV^-IO К) are obtained. Neutral HI and ionized H II hydrogen maps show non-symmetrical hydrogen distribution. Dust and gas maps indicate the presence of spiral and toroidal disk structure
