One-dimensional inorganic crystals composed of heavy atoms with broken spatial inversion symmetry and anisotropic structures exhibit unique physical phenomena not observed in higher dimensional semiconductors such as Si. In this study, we aim to control the spatial inversion symmetry and develop novel optical/spin properties in inorganic one-dimensional structures containing Pb²⁺, Bi³⁺ and Te⁴⁺ by using chiral organic molecules. Here, we report on the structure and photoelectric conversion properties of one-dimensional chiral single crystals based on bismuth iodide and tellurium iodide.
