The composition and structure of homogeneous SiC1.4, SiC0.95, SiC0.7, SiC0.4, SiC0.12, and SiC0.03 layers obtained by multiple high-dose implantation of carbon ions with energies of 40, 20, 10, 5, and 3 keV into silicon are analyzed using Auger electron spectroscopy, X-ray diffraction, IR spectroscopy, and atomic force microscopy. The effect of decomposition of carbon and carbon-silicon clusters on the formation of Si-C tetrahedral bonds and on crystallization in silicon layers with high and low concentrations of carbon is considered. © 2011 Pleiades Publishing, Ltd.

We study the behavior of the QCD effective coupling α s in the low-energy region by exploiting the conventional meson spectrum within a relativistic quantum-field model based on analytical confinement of quarks and gluons. The spectra of quark-antiquark and two-gluon bound states are defined by using a master equation similar to the ladder Bethe-Salpeter equation. A new, independent and specific infrared-finite behavior of QCD coupling is found below energy scale ~1 GeV. Particularly, an infrared-fixed point is extracted at α s(0) ≅ 0. 757 for confinement scale Λ = 345 MeV. We provide a new analytic estimate of the lowest-state glueball mass. As applications, we also estimate masses of some intermediate and heavy mesons as well as the weak-decay constants of light mesons. By introducing only a minimal set of parameters (the quark masses m f and Λ) we obtain results in reasonable agreement with recent experimental data in a wide range of energy scale ~0. 1-10 GeV. We demonstrate that global properties of some low-energy phenomena may be explained reasonably in the framework of a simple relativistic quantum-field model if one guesses correct symmetry structure of the quark-gluon interaction in the confinement region and uses simple forms of propagators in the hadronisation regime. The model may serve a reasonable framework to describe simultaneously different sectors in low-energy particle physics. © 2012 Pleiades Publishing, Ltd.

Self-organization of highly ordered mosaic structure of porous Si at long anodic etching of p-Si (100) in electrolyte with internal source of the current is observed. Sizes of the nanocrystallites islets of porous Si, the period of their location and self-organization of the mosaic structure of porous silicon are defined by the effect of forces of elastically-deformation, defectdeformation and capillary-fluctuation that exist at the interface of electrolyte/porous Si/c-Si/ in process of pores formation. Process of spontaneous formation of mosaic structure por-Si has place in results from relaxation of the elastically-strained layer of porous surface and effect of capillary-fluctuation forces. Conditions of development of these forces depend on the self-coordinated parameters of etching of interface heterophase of electrochemical system the electrolyte/porous Si/c-Si/ and parameters of electrodes and electrochemical cell. © 2011 IEEE.

The influence of treatment in hydrogen and oxygen glow discharge plasmas on the structural and optical properties of 270- to 350-nm-thick SnOx films prepared using magnetron sputtering and the sol-gel method on the glass substrate has been considered. It has been demonstrated that the plasmas exert segregating and destroying effects on the structure of crystal grains, the transparency of films, and on their porosity. It has been established that treatment in the hydrogen glow discharge plasma makes it possible in principle to prepare crystal-amorphous nanostructures in which tin oxide nanocrystals of high quality alternate with tin oxide clusters. © 2011 Pleiades Publishing, Ltd.
