    Abstract: There is a method for making a high-performance opto-electronic device (1300) on an amorphous substrate. The method includes growing (1600) on a single-crystal substrate (1304), a single-crystal, oxide film (1302); applying a first chemical processing (1602) to the single-crystal, oxide film (1302) to obtain a first transferrable, single-crystal, chalcogenide film (1308); transferring (1604) the transferrable, single crystal, chalcogenide film (1308) from the single-crystal substrate (1304) to an amorphous substrate or polycrystalline metal substrate (1316); applying a second chemical processing (1606) to the transferrable, single-crystal, chalcogenide film (1308) to obtain a single-crystal, non-oxide film (1320), wherein the single-crystal, non-oxide film (1320) is different from the transferrable, single-crystal, chalcogenide film (1308); and growing (1608) a wide-bandgap semiconductor film (1324) using the single-crystal, non-oxide film (1320) as a seeding layer to obtain the opto-electronic device (1300) on the amorphous glass or polycrystalline metal substrate. The first chemical processing is different from the second chemical processing.
