## Description

- description: Tunneling light-emitting devices (LEDs) based on transition metal dichalcogenides
    (TMDs) and other 2D materials are a new platform for on-chip optoelectronic integration.
    Some of the physical processes underlying this LED architecture are not fully
    understood, especially the emission at photon energies higher than the applied
    electrostatic potential, so-called overbias emission. Here we report overbias
    emission for potentials that are near half of the optical bandgap energy in TMD-
    based tunneling LEDs. We show that this emission is not thermal in nature, but
    consistent with exciton generation via a two-electron coherent tunneling process.
