Broadband Photodetectors In article number 2103429, Xiangang Luo and co‐workers report a broadband photodetector utilizing GaTe after breaking through its bandgap limitation by self‐driven O 2 intercalation in air and further reveal its anisotropic nature of both intrinsic and extrinsic photoconductivity. This provides design strategies of 2D materials‐based high performance broadband photodetectors for the exploration of the polarized state information.
