Breaking the Cut‐Off Wavelength Limit of GaTe through Self‐Driven Oxygen Intercalation in Air (Adv. Sci. 9/2022)

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.
