## Description

- description: The surface conductivity of hydrogen-terminated diamond is a topic
    of great interest from both scientific and technological perspectives. This is
    primarily due to the fact that the conductivity is exceptionally high without
    the need for substitutional doping, thus enabling a wide range of electronic applications.
    Although the conductivity is commonly explained by surface transfer doping due
    to air-borne surface acceptors, there remains uncertainty regarding the main determining
    factors that govern the degree of band bending and hole density, which are crucial
    for the design of electronic devices. Here, we elucidate the dominant factor influencing
    band bending by creating shallow nitrogen-vacancy (NV) centers beneath the hydrogen-terminated
    diamond surface through nitrogen ion implantation at varying fluences. We measured
    the photoluminescence and optically detected magnetic resonance (ODMR) of the
    NV centers, as well as the surface conductivity, as a function of the nitrogen
    implantation fluence. The disappearance of the conductivity with increasing nitrogen
    implantation fluence coincides with the appearance of photoluminescence and ODMR
    signals from negatively charged NV centers. This finding indicates that band bending
    is not exclusively determined by the work-function difference between diamond
    and the surface acceptor material, but by the finite density of surface acceptors.
    This work emphasizes the importance of distinguishing work-function-difference-limited
    band bending and surface-acceptor-density-limited band bending when modeling the
    surface transfer doping, and provides useful insights for the development of devices
    based on hydrogen-terminated diamond.
