Patent ID: 8178221

Claim:
A flexible, polycrystalline, electronic device article comprising; a. a large-grained, polycrystalline, annealed metal or alloy substrate with a primary or secondary recrystallization texture corresponding to {100}<100>, with a mosaic of less than 10 degrees; b. at least one polycrystalline, buffer layer on said substrate selected from a group consisting of a metal, an alloy, a nitride, boride, oxide, fluoride, carbide, silicide, intermetallic alloy with germanium or combinations thereof, having a crystallographic texture corresponding to a single {100}<100> or a 45°-rotated {100}<100> texture; c. at least one epitaxial, polycrystalline, semiconductor device layer on said buffer layer having a crystallographic texture corresponding to a single orientation, {100}<100> or a 45°-rotated {100}<100> texture.
