## Description

- description: Deep ultraviolet (DUV) photodetectors (PDs) based on ultra-wide bandgap
    semiconductor diamond-based have attracted extensive attention due to the immunity
    to solar light on the earth and thermal stability in extremely harsh environments.
    However, the preparation of a high-quality and high-purity single-crystal diamond
    epilayer remains a major obstacle to achieve high photo-response performance.
    Here, we demonstrate that diamond PDs with tunable photoresponse properties can
    be obtained on type-Ib diamonds through simple annealing in ambient H2 and a surface
    ozone treatment process. The surface holes and the nitrogen defects inside the
    type-Ib diamond work together to regulate the overall photoresponse performance.
    The responsivity of the PDs can be adjusted from 84.3 A W−1 to 2.65 × 104 A W−1,
    and the response time can be modulated from 42.5 s to less than 240 ms. The achievement
    of photo response performance modulation of PDs originates from the cooperative
    effect of deep natural nitrogen defects and surface states. Thus, our findings
    provide an alternative method and facile strategy for the tailoring of PDs’ performance,
    which can meet different application requirements.
