The method of Rutherford back scattering of He + ions with 2 MeV studied the distribution profiles of the elements C, Cu and W in the films deposited on the discharge installation type "plasma focus". The films are deposited on glass substrates in Ar plasma-forming gas. It is found that the element distribution profiles vary significantly from the kinetic energy of the particles. Particles having a velocity about 105 m / s, penetrates to a depth of about 1.5 microns. Appropriate distribution profiles elements for glass thickness are nonlinear. For each element, there is a maximum depth of the layer under the surface of the glass. A feature of the films obtained on the setting of "plasma-focus" is the formation of layers of the elements Cu, W and C at the glass surface and their mutual overlap. This arrangement of layers distinguishes described film deposition method of the commonly used methods of application at low speeds the deposition of atoms, as well as by diffusion. It is found that the obtained film are insulators.
X-ray topography is a complex of X-ray diffraction methods allowing one to detect the images of defects, to
determine their type, the arrangement in a crystal structure volume or on its surface, to measure their basic
characteristics. The possibilities, limitations and prospects of X-ray topography methods are discussed in the
Single crystals and films of 2-methylbenzimidazole were obtained by evaporation from an alcohol solution. Films are a texture with a predominant orientation of the pseudo-tetragonal axis in the film plane. The blocks are split spherulite-type crystals in which the pseudotetragonal axis rotates around the center of the block. Dielectric hysteresis loops in the temperature range 290-350 K were studied in crystals and films. In films, loops are observed in an electric field directed both parallel and perpendicular to the film plane. The maximum value of polarization in films is close to that observed in single crystals (P s ~5 µcl / cm2). The difference in the temperature behavior of hysteresis loops in crystals and films is associated with the specific structure of the blocks.
