It is demonstrated that in the process of vacuum deposition of thin films it is desirable to employ laser heating of the films in order to stabilize their properties. A setup in which the same laser… (More)
The first-order Raman scattering in isotopically enriched samples of germanium 70Ge, 72Ge, and 74Ge and germanium with the natural isotopic composition is investigated at high pressures. It is found… (More)
Abstract The development of multilayer coatings prepared by physical vapour deposition (PVD) for piston rings of internal combustion engines to decrease the wear of both ring and cylinder is… (More)
We report the discovery of superconductivity in SnSe with Tc around 4.5 K at pressures exceeding 58 GPa. It is conjectured that the high-pressure superconducting modification has the CsCl structure.
