The integration of a chiral halide perovskite semiconductor into a light-emitting diode (LED) structure made from a III–V optoelectronic semiconductor creates a spin-LED that achieves 15% circularly polarized emission at room temperature without a magnetic field — a potential boon for spintronics and other spin‑based technologies.
