  • Patent number: 6638598
    Abstract: A laminate includes an amorphous or polycrystalline substrate; a textured buffer layer arranged on the substrate and having a columnar structure wherein a low index crystal axis is inclined with respect to the substrate normal and a surface of columnar crystallites is inclined with respect to the low index crystal axis; at least one cover layer arranged on the buffer layer and having a closed surface; and an oriented thin layer.

  • Patent number: 6265353
    Abstract: In a method for producing laminate, a buffer layer is applied to a substrate, with the buffer layer material being evaporated from the buffer layer material dispensing devices at an angle &agr;1≠0 at the normal to the substrate surface onto the latter, before an oriented thin layer is evaporated. According to the invention, provision is made such that (a) following evaporation of the buffer layer and prior to the evaporation of the oriented thin layer, at least one cover layer is evaporated under deposition conditions that vary from those under which the buffer layer was applied, especially at a different pressure, different temperature, different rate, and/or different angle &agr;2≠&agr;1, especially &agr;2<&agr;1, preferably &agr;2≈0° to the substrate surface normal, and/or is evaporated on the buffer layer in such fashion that the buffer layer has a biaxial texture and/or facets.

  • Publication number: 20010007707
    Abstract: The invention relates to a laminate with, one after the other, amorphous or polycrystalline substrate, a textured buffer layer, and an oriented thin layer. In addition, at least one cover layer is contained between the buffer layer and the thin layer. In a method for producing laminate, a buffer layer is applied to a substrate, with the buffer layer material being evaporated from the buffer layer material dispensing devices at an angle &agr;1≠0 at the normal to the substrate surface onto the latter, before an oriented thin layer is evaporated.
