Abstract

Al_0.16Ga_0.84N 320nm near-solar-blind ultraviolet (UV) metal-semiconductor-metal photodetectors (MSM-PDs) with a low-temperature AlN (LTAlN) layer and inductively coupled plasma (ICP) recessed electrodes were successfully fabricated. Compared with the conventional MSM-PDs, it was found that the measured photocurrent was much larger for the MSM-PD with the LT-AlN layer and ICP recessed electrodes. The responsivity of the MSM-PD with the LT-AlN layer and ICP recessed electrodes was also found to be larger, which could be attributed to the ICPetching-induced photoconductive gain.
