## Description

- description: Controlling interlayer excitons in van der Waals heterostructures holds
    promise for exploring Bose-Einstein condensates and developing novel optoelectronic
    applications, such as excitonic integrated circuits. Despite intensive studies,
    several key fundamental properties of interlayer excitons, such as their binding
    energies and interactions with charges, remain not well understood. Here we report
    the formation of momentum-direct interlayer excitons in a high-quality MoSe<sub>2</sub>/hBN/MoSe<sub>2</sub>
    heterostructure under an electric field, characterized by bright photoluminescence
    (PL) emission with high quantum yield and a narrow linewidth of less than 4 meV.
    These interlayer excitons show electrically tunable emission energy spanning ~180
    meV through the Stark effect, and exhibit a sizable binding energy of ~81 meV
    in the intrinsic regime, along with trion binding energies of a few millielectronvolts.
    Remarkably, we demonstrate the long-range transport of interlayer excitons with
    a characteristic diffusion length exceeding 10 μm, which can be attributed, in
    part, to their dipolar repulsive interactions. Spatially and polarization-resolved
    spectroscopic studies reveal rich exciton physics in the system, such as valley
    polarization, local trapping, and the possible existence of dark interlayer excitons.
    The formation and transport of tightly bound interlayer excitons with narrow linewidth,
    coupled with the ability to electrically manipulate their properties, open exciting
    new avenues for exploring quantum many-body physics, including excitonic condensate
    and superfluidity, and for developing novel optoelectronic devices, such as exciton
    and photon routers.
