摘要
石墨烯具有超高载流子迁移率、零带隙、宽波段响应等性质,是具有潜力的红外光电探测材料。通过分析石墨烯基红外探测器的发展历程,综述了石墨烯红外光电响应的机理,对石墨烯基探测器的响应度、波段、速度等性能和器件结构进行了梳理,并围绕石墨烯基探测器在材料制备、工艺兼容性等方面的挑战进行了探讨和展望。
Graphene has some unique properties, such as ultra-high carrier mobility, zero band gap,broadband response, which make it a promising material in infrared photodetection. In this review, the development history of graphene-based infrared detectors was analyzed, and the mechanism of relevant photoelectric response was summarized. The responsivity, wave-band, response speed and device structure were sorted out. The challenges of material preparation and process compatibility of graphene-based detectors were also discussed and prospected.
