 Objects of study are PbS-PbSe superlattices, Vi films, Ti-Zr-Ni amorphous films, diamond-like carbon coatings and nanostructures, film ferro-probes, quantum coherent systems. The purpose of the work is to study new physical phenomena in nano-objects, to create new film materials and nanoscale systems based on them and to use them to create devices. Research methods - X-ray diffractometry, electron scanning and electron microscopy, measurements of mechanical, magnetic, noise, electrophysical, electrochemical properties and others. New results: For the first time, for the PbSe-PbS system, the change in the intensity of the satellite reflexes determined the effective coefficients of interdiffusion of the nanoscale materials of the layers. By deposition of C60 from an ion-molecular beam obtained a superhard diamond amorphous carbon coating, which is 100-400 times greater than the wear resistance of the surface of titanium and cobalt chromium alloy. It has been experimentally proved that deposition of carbon nanocomposite coatings significantly increases the biological compatibility of the material. It is proposed to use periodic voltage pulses for temporal spectroscopy of quantum coherent structures. A distinctive feature of our time spectroscopy method is that the charge pulse behavior resembles that of a particle, but still remains sensitive to quantum carrier statisticscurrently. This unique combination makes our circuit promising for the characterization of quantum coherent circuits and provides a practical alternative to measuring frequency-dependent electrical noise.
