Abstract
The authors theoretically report a plasmonic photodetector based on graphene-black phosphorus heterostructure which is capable of operating from visible to mid-infrared (MIR) wavelengths. The combination of plasmonic nanostructure and graphene-black phosphorus heterostructure can significantly enhance the absorption, simulation results show that the proposed photodetector is capable of working from 400 nm to 3 μm with ultrahigh responsivity all exceeding 14,000 AW−1 and large modulation bandwidth all over 327 GHz. In addition, by utilising the evident anisotropic characteristics of black phosphorus, the broadband plasmonic photodetector exhibits the angle-dependent responsivity which can be used to design the customised plasmonic photodetector. The authors believe that the proposed photodetector would provide the new approach to design the broadband and angle-dependent optoelectronic devices based on 2D materials.
