## Description

- description: 'Two-dimensional materials such as monolayer WSe2 have prospective
    applications in quantum information science because of their capability to host
    single-photon emitters (SPE). However, chemical functionalization remains an unexplored
    parameter space in the design and control of SPE based on 2D materials, whose
    atomically thin structure should yield strong tunability with interfacial modifications.
    Moreover, SPEs in 2D materials are typically generated using a single mechanism
    such as strain. Here, we report a chemomechanical approach to modify SPEs by using
    a synergistic combination of localized mechanical strain and non-covalent functionalization
    with aryl diazonium chemistry. Following a facile diazonium treatment, the dense
    defect-related emissive states of strained monolayer WSe2 are simplified into
    spectrally-isolated SPE with high photon purity. Our work significantly broadens
    the possibilities in the parameter space of designing 2D materials-based SPEs
    by utilizing molecular heterojunction and chemical functionalization approaches. '
