Hybrid systems have recently attracted increasing attention, which combine the special attributes of each constitute and create interesting functionalities through multiple heterointerface interactions. Here, we design a two-dimensional (2D) hybrid phototransistor utilizing Janus-interface engineering, in which the WSe channel combines light-sensitive perovskite and spontaneously polarized ferroelectrics, achieving collective ultrasensitive detection performance. The top perovskite (BA(MA)PbI) layer can absorb the light efficiently and provide generous photoexcited holes to WSe.

- Circularly polarized light (CPL) is crucial for technologies in optoelectronics and chiro-spintronics, but is mainly found in chiral perovskites.
- A new method has been developed to induce CPL activity in achiral perovskites, which are known for their rich compositions and efficient luminescence.
- By creating van der Waals heterojunctions between chiral and achiral perovskites, spin-polarized electrons enhance CPL in achiral perovskites, resulting in significantly higher polarization degrees, with potential for flexible design via chemical tuning or temperature adjustments.
