Abstract

(NH₄)₂ S_x treatment was employed to enhance the efficiency of AlGaN metal-insulator-semiconductor (MIS) photodetectors (PDs) with a liquid phase deposited (LPD) SiO₂ layer. With (NH₄)₂ S_x treatment, one can reduce the reverse leakage current of the PD by 2 orders of magnitude and enhance the effective Schottky barrier height from 0.77 to 0.86 eV. Also, the (NH ₄)₂ S_x treatment can also significantly reduce the interface state density, Dit, at the AlGaN/LPD oxide interface. Photo-to-dark current ratio observed from the PDs with (NH₄) ₂ S_x treatment was also significantly larger.
