a Cross-sectional SEM image of our CPL detector. Note: The visible cracks in the image are artifacts resulting from the gold coating process used for imaging, and do not affect the integrity of the device layers. Response spectra of the CPL detectors based on R-2D/3D (b) and S-2D/3D (c) perovskite under σ+ and σ− CPL illumination, respectively. d The gcurrent spectra of the detectors based on R-2D/3D, rac-2D/3D, and S-2D/3D perovskite. e The photocurrent differences of S-2D/3D detector under σ+ and σ− CPL illumination (532 nm) at 0 V. f The gCD and gcurrent spectra of the CPL detectors based on pure R-MBA2PbI4 and S-MBA2PbI4. The gCD was calculated using the formula gCD = CD/(32980×absorbance) based on Supplementary Fig. 15. The gcurrent was calculated using Eq. (1), as detailed in Supplementary Fig. 16. g Schematic diagram of the mechanism of chiral-2D/3D-based CPL detectors based on spintronic properties. Source data are provided as a Source Data file.
