New publication: Enhancement of silicon sub-bandgap photodetection by helium-ion implantation

In collaboration with researchers from the University of Science and Technology of China, Huazhong University of Science and Technology, and Zhejiang University-UIUC Institute, our group used a helium-ion microscope to implant helium ions into silicon with appropriate doses to improve the performance of photodetectors based on sub-bandgap optical absorption effects.
