The disclosed method involves producing a high-quality LnCuOX single-crystal thin film. It includes growing a base thin film on a single-crystal substrate, depositing an amorphous or polycrystalline LnCuOX thin film on top to form a laminated film, and annealing the laminated film at a temperature of 500°C or higher. This method enables the growth of a thin film with excellent crystallinity suitable for use in light-emitting diodes, semiconductor lasers, field-effect transistors, and hetero-bipolar transistors, surpassing the limitations of conventional polycrystalline films.
