## Description

- description: Boron vacancies in hexagonal boron nitride (hBN) are among the most
    extensively studied optically active spin defects in van der Waals crystals, due
    to their promising potential to develop two-dimensional (2D) quantum sensors.
    In this letter, we demonstrate the tunability of the charge state of boron vacancies
    in ultrathin hBN layers, revealing a transition from the optically active singly
    negatively charged state to the optically inactive doubly negatively charged state
    when sandwiched between graphene electrodes. Notably, there is a photoluminescence
    quenching of a few percent upon the application of a bias voltage between the
    electrodes. Our findings emphasize the critical importance of considering the
    charge state of optically active defects in 2D materials, while also showing that
    the negatively charged boron vacancy remains robust against external perpendicular
    electric fields. This stability makes it a promising candidate for integration
    into various van der Waals heterostructures.
