Fast-Response Vertical-Structure Two-Dimensional Perovskite Photodetector
A vertical-structure photodetector based on two-dimensional perovskite (PEA)2(MA)4Pb5I16[PEA is C6H5(CH2)NH3, MA is CH3NH3] is fabricated and its property is analyzed. The photocurrent of the device reaches a maximum when the thickness of the two-dimensional perovskite thin film is 280 nm, while at 500 nm, the external quantum efficiency reaches 90%, the responsivity reaches 0.37 A/W, and the detectivity reaches 3.4×1012 Jones(1 Jones=1
