    Hydrogen Plasma Treatment

## Description

- description: Diamond-based solar blind deep ultraviolet (DUV) photodetectors (PDs)
    have attracted extensive attention due to their unique characteristics in extremely
    harsh environment. Until now, its low responsivity has not been sufficient to
    meet the needs of the application. Here, an ultrahigh performance diamond-based
    solar blind DUV PD was obtained by controlling the two-dimensional hole carrier
    concentration on the epilayer-free Ib-type diamond surface through adjusting the
    duration of hydrogen plasma treatment. The diamond-based PD with 30 min hydrogen
    plasma treatment exhibits an ultrahigh external quantum efficiency (EQE) of 9.4×106%,
    which are far superior to the previously reported diamond-based, AlGaN-based,
    and Ga2O3-based solar blind PDs. These results open up a facile route to prepare
    high-sensitivity photodetectors
