Low-dimensional Ga2O3 monocrystalline micro/nanostructures show promising application prospects in largearea arrays, integrated circuits, and flexible optoelectronic devices, owing to their exceptional optoelectronic performance and scalability for mass production. Herein, we developed an 8 x 8 array of high-performance solar-blind ultraviolet photodetectors based on Pt nanoparticles-modified Ga2O3 (PtNPs@Ga2O3) nanorod film heterojunction with p-GaN substrate serving as the hole transporting layer. The PtNPs@Ga2O3/GaN heterojunction detector units exhibit outstanding photovoltaic performance at 0 V bias, demonstrating high responsivity (189.0 mA/W), specific detectivity (4.0 x 1012 Jones), external quantum efficiency (92.4%), and swift response time (674/692 mu s) under an irradiance of 1 mu W/cm2 at 254 nm. Their exceptional performance stands out among competitors of the same type. In addition, the detector array demonstrated satisfactory results in a conceptual demonstration of high-resolution imaging, benefiting from the excellent stability and uniformity exhibited by its array units. These findings provide a straightforward and viable method for developing a high-performance solar-blind ultraviolet detector array based on low-dimensional Ga2O3 nanorod monocrystalline, demonstrating their potential advancement in large-area, integrable, and flexible optoelectronic devices.

近年来,氧化镓(Ga_(2)O_(3))是新一代超宽禁带(4.9 eV)半导体,基于优越的热稳定和化学稳定性、高击穿场强和可见光透过率等优点,在日盲紫外探测器和透明光电器件领域中引起了广泛的关注.但是,Ga_(2)O_(3)基光电器件存在迁移率较低而限制其应用的现象,而构建合适的Ga_(2)O_(3)异质结是改善光电探测器的光电性能的有效手段之一.基于第一性原理构建β-Ga_(2)O_(3)/BP异质结模型,研究了氧空位(Vo)和Si掺杂对β-Ga_(2)O_(3)/BP异质结光电性质的调控以及相关机理.结果显示:β-Ga_(2)O_(3)/BP异质结结构有效降低β-Ga_(2)O_(3)功函数,提高灵敏度,Si掺杂降低结合能,增强稳定性;β-Ga_(2)O_(3)/BP异质结有效减小带隙,Si掺杂以及氧空位的存在,进一步减小带隙,增强光导电性,并且Si掺杂引起了光电导各向异性.此结果对改善Ga_(2)O_(3)基异质结光电性能提供理论参考.
