a Schematic diagram of circular polarization-sensitive vision system of mantis shrimp. The left panel exhibits the frontal view of the compound eye structure composed of the dorsal hemisphere (DH), ventral hemisphere (VH), and midband (MD) between them. The middle panel illustrates the DH and VH structures in detail. The right panel is the microvillar projections from two retinular cells constructing stacked layers in the rhabdom. The enlarged part shows the orientation of microvilli in alternate layers of rhabdom. The mantis shrimp image was rendered from the royalty-free 3D model from Turbosquid. DH, VH, and the enlarged parts are redrawn from ref. 6. b Structural scheme of the in-plane 1D-S/SWNTs heterostructure device. c Energy band diagram of H-PVK/SWNTs heterostructure (Evac is the vacuum energy level, EF is the Fermi energy level). d CD spectra of H-PVK (1D-R, 1D-S)/SWNTs heterostructures. e Current-voltage curves of 1D-S/SWNTs heterostructure under dark, LCP, and RCP (395 nm, 10 μW cm−2) illumination. f Responsivity of H-PVK/SWNTs under RCP and LCP at the wavelengths of 375 nm, 395 nm, 430 nm and 447 nm (10 μW cm−2). g Photocurrent and responsivity under the incident 395 nm LCP at different intensities.
