## Description

- description: Spin-polarized light-emitting diodes (spin-LEDs) convert the electronic
    spin information to photon circular polarization, offering potential applications
    including spin amplification, optical communications, and advanced imaging. The
    conventional control of the emitted light's circular polarization requires a change
    in the external magnetic field, limiting the operation conditions of spin-LEDs.
    Here, we demonstrate an atomically thin spin-LED device based on a heterostructure
    of a monolayer WSe2 and a few-layer antiferromagnetic CrI3, separated by a thin
    hBN tunneling barrier. The CrI3 and hBN layers polarize the spin of the injected
    carriers into the WSe2. With the valley optical selection rule in the monolayer
    WSe2, the electroluminescence exhibits a high degree of circular polarization
    that follows the CrI3 magnetic states. Importantly, we show an efficient electrical
    tuning, including a sign reversal, of the electroluminescent circular polarization
    by applying an electrostatic field due to the electrical tunability of the few-layer
    CrI3 magnetization. Our results establish a new platform to achieve on-demand
    operation of nanoscale spin-LED and electrical control of helicity for device
    applications.
