Heterointerface-Functionalized Photoelectric Response of Metal-Oxide Schottky Photodiode for Intelligent Fire Detection.

ABSTRACT: Ultraviolet photodetectors (UV-PDs) based on wide-bandgap oxide semiconductors (OSs) hold broad prospects in scientific, civil, and especially fire alarm applications. However, the hotly pursued flexible and hetero-integration capabilities are hindered by the high processing temperature of mainstream Ga₂O₃ UV-PDs, while the selective UV detection capability of low-temperature OS (LT-OS) is undermined by the pronounced contradictory effects of abundant native defects on electric and optoelectrical properties. Herein, a heterointerface-functionalized Schottky photodiode (HF-SPD) is proposed to realize high-performance LT-OS UV-PD. Due to the sophistically modulated Schottky contact and defect distribution, ultralow dark current and remarkable photoresponse are simultane
