Solar-blind imaging has attracted considerable interest in both military and civilian applications,spurring the development of high-performance deep-ultraviolet photodetector arrays(PDAs) with wide-bandgap semiconductor materials.Herein,we present a novel method to enhance the performance of solar-blind PDAs(SBPDs) using β-Ga_(2)O_(3) films obtained by the phase transition of heterogeneous epitaxial sub-stable ε-Ga_(2)O_(3),achieved through high-temperature rapid annealing.Metal-semiconductor-metaltype SBPDs based on phase-transformed β-Ga_(2)O_(3) films exhibited superior performance,including an ultrahigh responsivity of 459.38 A/W,detectivity of 10^(14)–10^(15) Jones,external quantum efficiency of 10^(4)%–10^(5)%,rejection ratio(R_(254)/R_(365)) of 10^(5)–10^(6),photo-to-dark current ratio of 10^(4)–10^(6),fast response speed of 1.01 s/0.06 s,and favorable stability.Notably,the ultrahigh responsivity of β-Ga_(2)O_(3)-film-based devices was approximately 222-fold higher than that of ε-Ga_(2)O_(3) film-based devices.The assembled 4×5 β-Ga_(2)O_(3) film-based PDAs exhibited favorable uniformity,repeatability,and high spatial resolution for solarblind imaging.Our study offers a promising approach for the development of high-performance β-Ga_(2)O_(3)-based PDAs for solarblind ultraviolet imaging with potential applications in both military and civilian fields. 展开更多
