| 英文摘要 | In this paper, comparison between back-illuminated p-i-n AlGaN-based ultraviolet photodetectors (UV-PDs) with and without an n-AlGaN inserted layer is carried out. The results show that the introduction of n-AlGaN interlayer significantly reduces the dark current of AlGaN-based UV-PDs. The mechanism involved is clarified and can be attributed to the role of n-AlGaN interlayer which depletes to isolate the leakage paths generated by dislocations of AlGaN material. Besides, it also greatly improves the spectral performances of the p-i-n AlGaN-based UV-PDs, which can be related to the additional built-in electric fields introduced by n-AlGaN inserted layer that contribute to separate and transport the photon-generated carriers. |
