## Description

- description: Single spin defects in 2D transition-metal dichalcogenides are natural
    spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence
    spectroscopy from three emission lines (Q1, Q2 and Q*) of He-ion induced sulfur
    vacancies in monolayer MoS2. Analysis of the asymmetric PL lineshapes in combination
    with the diamagnetic shift of Q1 and Q2 yields a consistent picture of localized
    emitters with a wavefunction extent of 2-3nm. The distinct valley- Zeeman splitting
    in out-of-plane B-fields and the brightening of dark states through in-plane B-fields
    necessitates lifting of the spin-degeneracy at zero field. Comparing our results
    to ab-inito calculations unambiguously identifies the nature of Q1 and Q2 and
    suggests that Q* is the emission from a chemically functionalized defect. Analysis
    of the optical degree of circular polarization reveals that the Fermi level is
    a parameter that enables the tunability of the spin-defect. These results highlight
    that defects in 2D semiconductors may be utilized for quantum technologies.
