Brief description of the growth of a monocrystalline film on a substrate when it is not match between the materials constituting the film and of the substrate and the structure in the resultant

摘要

P process of growth of a monocrystalline film on a substrate when it is not match between the materials constituting the film and of the substrate and the structure in the resultant. / p & & p & a monocrystalline substrate 10, typically of sodium chloride, is firstly covered epitaxially by deposition under vacuum, of islets 12 made of nickel hemispherical shape, and then by epitaxial deposition under vacuum of a monocrystalline layer of silver, 13, followed by the epitaxial deposition under vacuum of a monocrystalline layer of gold 14. The use of islets makes it possible to reduce # considerably the defects generated by the non - agreement of the materials. / p & & p & application in particular in the industry of semi - conductors, or this process can be used for the deposition of silicon on alumina. / p
