Significant endeavors have been undertaken to develop waveguide photodetectors for silicon photonics by integrating various 2D materials such as graphene and BP, as outlined in Table 2. The exceptional carrier mobility of graphene, in particular, holds significant potential for the fabrication of high-speed waveguide photodetectors on silicon.
