将复位MOSFET添加到基于钙钛矿MOSFET的光电探测器中，作为电流源，以减轻离子运动对光电探测器性能的影响。加入MOSFET后，迟滞显著减小，暗电流可控。开关比恢复到106，并且在仅13 nW/cm2的红光（665 nm）光强下实现超灵敏的响应度（超过80,000 A/W）。
A Reset MOSFET is added to a perovskite MOSFET-based photodetector to serve as a current source to mitigate the influence of ionic movement on the performance of the photodetector. With the added MOSFET, the hysteresis is significantly reduced, and the dark current is controllable. The on/off ratio resumes to 106 and an ultrasensitive responsivity (over 80, 000 A/W) is achieved under only 13 nW/cm2 red (665 nm) light intensity.
