a) The schematic of the ReS₂‐based photodetection device under illuminating polarized light by the half wave plate. The photocurrent response as a function of drain voltage under b) different light intensity green light illumination, c) different polarization light illuminations, and d) different drain biases. Reproduced with permission.28 e) The schematic structure of ReSe₂ photodetectors. The half‐wave plate was used to change the polarization direction. f) I _ds–V _ds of the photodetector with incident laser power varied from 0 to 20 µW. Inset: Small range of I _ds–V _ds with different incident laser powers. g) Scanning electron microscope (SEM) image of the polarization‐dependent photocurrent mapping of ReSe₂ photodetector, showing prominent linear dichroic photodetection.
