  However, polarization-sensitive two-dimensional (2D) photodetectors are typically limited to a narrow range of intrinsically anisotropic materials, which suffer from poor polarization discrimination, environmental instability, and bandgap-limited photoresponse in the SWIR region.

  Although on-chip polarized photodetectors have been realized in recent years based on two-dimensional (2D) materials with low-symmetry crystal structures, they are limited by the intrinsic anisotropic property and thus the optional range of materials, the operation wavelength, and more importantly, the low anisotropic ratio, hindering their practical applications.

  Abstract Polarization-sensitive two-dimensional (2D) photodetectors are important for imaging, optical communication, and weak-signal recognition, yet their performance is often limited by the intrinsic anisotropy of the 2D semiconductor channel alone.
