To cultivate innovative talents,combined with the teaching content of electronic science and technology,a research experiment teaching design for"A self-power β-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 X-ray diffractometer and scanning electron microscope.The prepared 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 is analyzed deeply.Integrating 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,innovative practice ability,scientific research,and exploration ability.
