主 题:organic-inorganic hybrid perovskite stability finite-difference time-domain photodetector
摘 要:Organic-inorganic hybrid perovskite formamidinium lead bromide nanosheet(FAPb Br_(3)NS)is regarded as a superior substance used to construct optoelectronic ***,its uncontrollable stability seriously affects its application in the field of *** this paper,FAPb Br_(3)is combined with cadmium sulfide nanobelt(Cd S NB)to construct a hybrid device that greatly improves the stability and performance of the *** response of the FAPb Br_(3)NS/Cd S NB detector under 490 nm light illumination reaches 5712 A/W,while the response of the FAPb Br_(3)photodetector under equivalent conditions is only 25.45 A/*** photocurrent of the FAPb Br_(3)NS/Cd S NB photodetector is nearly 80.25%of the initial device after exposure to air for 60 *** difference in electric field distribution between the single material device and the composite device is simulated by the finite-difference time-domain *** shows the advantages of composite devices in photoconductive gain and directly promotes the hybrid device *** paper presents a new possibility for high stability,fast response photodetectors.
