Chirality Versus Symmetry: Electron's Spin Selectivity in Nonpolar Chiral Lead–Bromide Perovskites (Adv. Mater. 51/2023)

Chiral Halide Perovskites In article number 2305784, Alexandre Abhervé, Mikaël Kepenekian, and co‐workers present the structural characterization, electronic properties calculations (band structure, spin texture) and the chirality‐induced spin selectivity (CISS effect) of 2D chiral halide perovskites. The importance of crystal symmetry for the spin polarization ability of this family of materials is revealed and the fabrication of chiro‐spintronic devices such as spin valves is demonstrated.
