Abstract
Novel articles and methods to fabricate the same resulting in flexible, oriented, semiconductor-based, electronic devices on {110}<100> textured substrates are disclosed. Potential applications of resulting articles are in areas of photovoltaic devices, flat-panel displays, thermophotovoltaic devices, ferroelectric devices, light emitting diode devices, computer hard disc drive devices, magnetoresistance based devices, photoluminescence based devices, non-volatile memory devices, dielectric devices, thermoelectric devices and quantum dot laser devices.
Claims38
A polycrystalline, electronic device comprising;
- a. a flexible, annealed, multigrain, metal or alloy substrate with a primary or secondary recrystallization texture corresponding to {110}<100>, with a mosaic or sharpness of texture of less than 10 degrees;
- b. at least one epitaxial, polycrystalline, semiconductor device layer on said substrate, with the semiconductor device layer having a crystallographic texture corresponding to a single orientation.
