Polarization-sensitive photodetection is central to optics applications and has been successfully demonstrated in photodetectors of layered hybrid perovskites; however, achieving high polarization sensitivity in such a photodetector remains challenging. Scientists based in China demonstrate a high-performance polarization-sensitive photodetector using single-crystalline 2D/3D perovskite heterostructure crystal, which exhibits ultrahigh polarization sensitivity up to 17.6 under self-driven mode. This work offers a new source of polarization-sensitive materials and provides insights into designing other advanced optoelectronic devices.
