AbstractPolarization-sensitive photodetectors can sense the polarization states of light.Traditional polarization-sensitive photodetectors usually require the incorporation of extra optical components such as polarizers and waveplates，resulting in bulky device and complex structure，which fails to meet the demand for miniaturization of devices.In this work，we have demonstrated linear polarization-sensitive photodetectors based on twisted stacked ReS 2 /MoSe 2 heterojunctions. Due to the formation of built-in electric field caused by the heterojunctions，the photodetectors can achieve optical response under zero bias voltage，with a maximum responsivity of 0.17A/W and a specific detectivity of 6×109 Jones. Meanwhile，photodetectors fabricated by combining two twisted stacked ReS2/MoSe2 heterojunctions can realize detection of arbitrary linear polarized light within a wide wavelength range of 600～800nm . This study provides a simple method for self-powered linear polarization-sensitive photodetectors.
