## Description

- description: Van der Waals materials have become a promising building block for
    future electronics and photonics. The two-dimensional magnet CrSBr came into the
    spotlight of solid state research due to its intriguing combination of antiferromagnetic
    order, strong light-matter coupling and unusual quasi-1D electronic band structure.
    This study reports the electrical excitation of excitons in CrSBr layers from
    cryogenic temperatures up to room temperature. By exploiting the energy transfer
    via tunneling electrons in a graphene tunnel junction strongly bound excitons
    are excited in proximate CrSBr layers. This facilitates electrically-excited emission
    from CrSBr crystals ranging in thickness from a bilayer up to 250 nm, in which
    the strong linear polarization of the electroluminescence confirms the excitonic
    origin. For thicker layers, clear evidence for the electrically excited emission
    from self-hybridized exciton polaritons is observed, highlighting the strong coupling
    between optical excitations and confined photon modes in CrSBr. These results
    pave the way for future applications in spintronic and optical readout of magnetic
    properties.
