Optical and electronic properties in amorphous BaSnO3 thin films

Wide-bandgap perovskite stannates are of interest for the emergent all-oxide transparent electronic devices due to their unparalleled room temperature electron mobility. Considering advantage amorphous material in integrating with non-semiconductor platforms, we herein reported optical and properties prototypical stannate, barium stannate (BaSnO3) thin films, which were deposited at annealed various temperatures. Despite remaining status, increasing annealing temperature, defect level within BaSnO3 films could be suppressed.
