Spin-polarized light-emitting diodes (spin-LEDs) convert the electronic spin information to photon circular polarization, but they are usually controlled only by external magnetic fields. Here, the authors report the realization of spin-LEDs based on 2D CrI3/hBN/WSe2 heterostructures, showing electrical tunability of the electroluminescence helicity.
