  • Patent number: 12637772
    Abstract: The present invention relates to a method for crystallization of a metal oxide thin film by using thermal dissipation annealing (TDA) and exhibits an effect enabling high-temperature thermal annealing, which is essential for the performance improvement of a semiconductor material, a sensor material, and the like deposited on a thin-plate substrate, even without degrading the performance of the thin-plate substrate. In addition, a metal oxide thin film prepared by the method of the present invention is in the form of a two-dimensional nanosheet, and thus may have a low defect density (high crystallinity) and a wide surface area. Accordingly, based on the improved photosensitivity and photoreactivity, the metal oxide thin film may be utilized in a high-performance photoelectric device.
