A novel low-symmetry two-dimensional heterojunction

Caption

A novel low-symmetry two-dimensional heterojunction (BP/Nb2SiTe4) is fabricated. This heterojunction photodetector features a broadband detection range of 360–2200 nm and a high dichroic ratio of 10.4, and it also achieves polarization-resolved imaging as well as polarization-encoded encryption and decryption functions, thus providing a new direction for the development of low-power, multifunctional polarization-sensitive photodetectors.
