摘　　要：采用限域诱导结晶法,通过溶液法制备有机小分子半导体TIPS并五苯、聚苯乙烯和钙钛矿量子点的光突触晶体管,研究薄膜的结构和光电性质,考察突触晶体管受到不同光刺激条件调控的突触性能和行为。聚苯乙烯发挥提高有机小分子半导体薄膜结晶度以及维持突触器件长程光电流的双重作用。同时,有机复合薄膜器件实现了图形感知和记忆功能,对发展人工视觉系统具有重要意义。The photonic synaptic transistor of organic small molecule semiconductor TIPS-pentacene,polystyrene and perovskite quantum dots was prepared by the solution method using the domain limited induced crystallization method.The film structure and photoelectric properties of the film were researched,and the synaptic properties and behavior of the synaptic transistor were investigated under different light stimulation conditions.The polystyrene played a dual role in improving the crystallinity of organic small molecule semiconductor films and maintaining long-term photocurrent of synapse devices.At the same time,organic composite thin film devices have achieved graphic perception and memory functions,which could be of great significance for the development of artificial vision systems.
