Description:

(abstract)

Diamond-based solar blind ultraviolet (UV) 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 UV PD was obtained by controlling the two-dimensional hole carrier concentration on the epilayer-free Ib-type diamond surface through adjusting the time of hydrogen plasma treatment. The diamond-based PD with 30 min hydrogen plasma treatment exhibits an ultrahigh responsivity of 16683 A/W and a superhigh external quantum efficiency (EQE) of 9.41×106%, 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-performance photodetectors.
