Abstract

Although black phosphorous (BP) is a promising two-dimensional material for next-generation infrared (IR) photodetectors, enhancing its quantum efficiency remains challenging. Herein, we proposed a hybrid BP–plasmonic nanograting with high aspect ratios for use in advanced functional IR photodetectors. Plasmonic nanogratings with high aspect ratios exhibit wide-angle near-unity absorption in the IR-wavelength region; this absorption is based on the grating depth. By forming BP on top of the plasmonic nanogratings and modifying the edge structure of BP, we achieved a hybrid structure that exhibits strong absorption. The results demonstrate the viability of BP-based high-performance IR photodetectors.
