| 英文摘要 | We report aGaN-based self-powered metal-semiconductor-metal (MSM)-type ultraviolet (UV) photodetector (PD) by employing a lateral polarity structure (LPS) grown on the sapphire substrate. An in-plane internal electric field and different Schottky barrier heights at a metal/semiconductor interface lead to efficient carrier separation and self-powered UV detection. A dark current of 6.8 nA/cm(2) and detectivity of 1.0 x 10(12) Jones were obtained without applied bias. A high photo-to-dark current ratio of 1.2 x 10(4) and peak responsivity of 933.7 mA/W were achieved for the lateral polarity structure-photodetector (LPS-PD) under 10 V. The enhanced performance of the LPS-PD was ascribed to the polarization-induced carrier separation as demonstrated by the lateral band diagram. (C) 2021 Optical Society of America |
