## Description

- description: Excitons -bound electron-hole pairs- play a central role in light-matter
    interaction phenomena, and are crucial for wide-ranging applications from light
    harvesting and generation to quantum information processing. A long-standing challenge
    in solid-state optics has been to achieve precise and scalable control over the
    quantum mechanical state of excitons in semiconductor heterostructures. Here,
    we demonstrate a technique for creating tailored and tunable potential landscapes
    for optically active excitons in 2D semiconductors that enables in-situ wavefunction
    shaping at length scales below 10nm. Using nanostructured gate electrodes, we
    create localized electrostatic traps for excitons in diverse geometries such as
    quantum dots and rings, and arrays thereof. We show independent spectral tuning
    of multiple spatially separated quantum dots, which allows us to bring them to
    degeneracy despite material disorder. Owing to the strong light-matter coupling
    of excitons in 2D semiconductors, we observe unambiguous signatures of confined
    exciton wavefunctions in optical reflection and photoluminescence measurements.
    Our work introduces a new approach to engineering exciton dynamics and interactions
    at the nanometer scale, with implications for novel optoelectronic devices, topological
    photonics, and many-body quantum nonlinear optics.
