论文摘要
半金属因其在低能高速光检测中的独特优势而被探索，尽管它们具有严重的缺点，例如本质上高的深色电流。从这个角度来看，我们设想了这些材料的光响应中拓扑效应的开发，这是解决这些问题的有前途的途径。我们概述了基于石墨烯和其他半法的近期对光反检测的研究，并进一步讨论了拓扑效应创造的令人兴奋的机会，以及它们对光电探测器设计的其他要求。
Semimetals are being explored for their unique advantages in low-energy high-speed photodetection, although they suffer from serious drawbacks such as an intrinsically high dark current. In this perspective, we envision the exploitation of topological effects in the photoresponse of these materials as a promising route to circumvent these problems. We overview recent studies on photodetection based on graphene and other semimetals, and further discuss the exciting opportunities created by the topological effects, along with the additional requirements that they impose on photodetector designs.
