Features of atomic and molecular beams passage through capillary systems in the presence of evanescent light waves

A model of the transverse cooling of atoms in the field of a surface light wave inside a glass capillary is considered. The attenuation coefficient for transverse oscillations of atom in a microcapillary is estimated, and the length of effective atom cooling is calculated. A 3D model is constructed. The possibility for the practical application of this phenomenon both to develop the technology of atomic lithography and to fabricate the nanostructures is considered

The influence of the substrate temperature change character during the growth on the topology of the Ge/Si(100) film surface

The possibility of roughness reducing of the Ge/Si (100) film using low-temperature layer of Ge (LT-Ge) has been investigated. It was shown that the substrate temperature change character during the growth process influences on the surface morphology of the grown Ge/LT-Ge/Si films. Samples were obtained by the method of molecular-beam epitaxy
