Solar-blind detectors play important roles in military and civilian affairs, due to their high signal-to-noise ratio and low-false alarm rate. In recent years, wide-bandgap semiconductor-based solar-blind photodetectors have been studied extensively. However, very little attention has been paid to position detection of solar-blind light. Herein, a solar-blind position-sensitive detector (PSD) is fabricated from β-Ga₂O₃/polycrystalline diamond heterojunctions. The solar-blind PSD shows good solar-blind response characteristics. In addition, the output signals of the PSD are dependent on the position of the solar-blind light spot, which can be utilized to realize position detection of solar-blind signals.

由 β-Ga2O3/多晶金刚石异质结制成的日盲位置敏感探测器

日盲探测器由于其高信噪比和低误报率在军事和民用事务中发挥着重要作用。近年来，基于宽带隙半导体的日盲光电探测器得到了广泛的研究。然而，很少有人关注日盲光的位置检测。在此，日盲位置敏感探测器（PSD）由β-Ga ₂ O ₃ /多晶金刚石异质结制成。日盲PSD显示出良好的日盲响应特性。此外，PSD的输出信号取决于日盲光斑的位置，可用于实现日盲信号的位置检测。
