## Description

- description: 'Optoelectronic functionalities of monolayer transition-metal dichalcogenide
    (TMDC) semiconductors are characterized by the emergence of externally tunable,
    correlated many-body complexes arising from strong Coulomb interactions. However,
    the vast majority of such states susceptible to manipulation has been limited
    to the region in energy around the fundamental bandgap. We report the observation
    of tightly bound, valley-polarized high-lying trions in monolayer TMDC transistors:
    quasiparticles composed of an electron from a high-lying conduction band with
    negative effective mass, a hole from the first valence band, and an additional
    charge from a band-edge state. Signatures of the associated p-like high-lying
    trion are identified from the excitonic quantum interference in second-harmonic
    generation. An electrical gate controls both the oscillator strength and the detuning
    of the excitonic transitions and therefore the Rabi frequency of the strongly
    driven three-level system, enabling excitonic quantum interference to be switched
    on and off in a deterministic fashion.'
