Uniform, highly porous, columnar thin films incorporating YSZ and NiO prepared by magnetron sputtering with deposition at glancing incidence exhibited stoichiometries close to that of the Y–Zr. Thin films of beryllium and gold that are several tens of nanometers thick were obtained, for the first time, on silicon and quartz substrates by the ion-beam method with tenfold alternation of deposition and partial sputtering of the nanosized metal layer. Mo thin films were sputtering deposited on glass substrates. Gold’s electrical resistivity is 0. In Au-Ag-Cu solid solutions, the color of the ternary alloy follows the rule of mixture. This two-step approach consists of the growth of gold/copper alloy nanowires by magnetron co-sputtering on a nanograted silicon substrate, serving as a physical template, followed by a selective. 99%.
