Polarization Sensitive Vacuum‐Ultraviolet Photodetectors Based on m‐Plane h‐BN

) of 24. The h-BN based detector achieves a high polarization ratio of 6.2 for 188 nm VUV polarized light, reaching the short-wavelength limit of the reported polarization-sensitive photodetectors. This work presents an effective strategy for designing polarized VUV photodetector from h-BN, and paves the road towards the novel integrated optoelectronics, photonics and electronics based on traditional 2D materials.
