摘要

为培养创新型人才，结合电子科学与技术专业的教学内容，设计了内容为“自驱动 α-Ga₂O₃/Cu₂O 双波段光电探测器”的研究性实验。采用水热法和光沉积法分别制备 α-Ga₂O₃纳米线和 Cu₂O 纳米颗粒，采用 X 射线衍射仪和扫描电子显微镜对纳米线进行了表征，通过合理设计器件的能带结构，所制备的 α-Ga₂O₃/Cu₂O 异质结光电探测器具备对深紫外和近紫外分辨探测的能力，并深入分析了其中的物理机制。将学术研究的探索精神融入实验中不仅可以提升实验的趣味性，还可以锻炼学生的自主学习能力、创新实践能力和科研探索能力。

Abstract:

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.

Key words: research experiment research guidance photodetector dual waveband band structure
