| 中文摘要: |
| 光电探测器在通信、检测和医疗等领域应用广泛，随着航空航天、夜视、遥感、热成像、汽车互联和消费电子等行业的发展，人们对超宽带探测器的需求也越来越迫切。现有的超宽带探测是使用不同材料、不同探测频段的多个光电探测器，集成度不高，阻碍了上述应用的发展。因此设计了石墨烯微米条–金属光栅复合结构的光电探测器，该器件在太赫兹、红外和可见光波段都可产生光电响应。在可见光范围内，金属光栅将探测器的探测灵敏度从1.1 mA/W显著提高至2.5 mA/W。该研究为基于石墨烯的超宽带光电探测器的设计提供了新的思路。 |

| Photodetectors are widely used in communication, detection, medical and other fields. With the development of industries such as aerospace, night vision, remote sensing, thermal imaging, automotive interconnection and consumer electronics, the demand for ultra-wideband photodetectors is increasing. Existing ultrawide band detectors are multiple photodetectors using different materials and different detection bands, which are poorly integrated and restrict the development of the above applications. We design a graphene micron strip-metal grating composite structure photodetector. It provides a photoelectric response in the terahertz, infrared and visible spectral regions. In the visible region, the metal grating significantly increased the detection sensitivity from 1.1 mA/W to 2.5 mA/W. This work provides new ideas for the design of graphene-based ultra-wideband photodetectors. |
