Abstract: In-plane anisotropic two-dimensional (2D) materials with asymmetric lattices are potential candidates for high performance polarized photodetection, which provides much richer optical information than conventional photodetection, such as polarization, azimuth, and ellipticity of the targets. Herein, non-layer structured ZnSb was grown into 2D nanostructures and used to fabricate room-temperature infrared polarized photodetectors. Studies found that the synthesized 2D ZnSb nanoplates exhibited strong in-plane electrical and optical anisotropy due to the low-symmetry crystal structure. The angle-resolved electronic and incident polarization photoelectric measurements confirmed high anisotropic conductivity and linear polarization sensitivity of the ZnSb nanoplates, which are consistent with the theoretical calculations.
