To cultivate innovative talents, combined with the teaching content of electronic scienee andtechnology , a research experiment teaching design for A self-power α-Ga₂O₃/Cu₂O dual-band photodetector’was designed.α-Ga₂O₃, nanowires and Cu₂O nanoparticles were prepared by hydrothermal method and photo-deposition.The nanowires were characterized by Xray diffractometer and scanning electron microscope. Theprepared α-Ga₂O₃/Cu₂O heterostructure photodetector was capable of detecting deep ultraviolet and near-ultraviolet resolution through the reasonable design of the device’s band structure. The physical mechanism isanalyzed deeply. lntegrating the exploration spirit of academic research into the experiment can not only enhance the interest of the experiment, but also exercise the students’ independent learning ability, innovativepractiee ability,scientife research, and exploration ability.
