Abstract: This study focuses on the development and fabrication of IDTBT nanowire/CsPbBr₃ perovskite composite thin-film transistors. Employing a micro/nano-confinement modulation strategy based on the organic polymer chains of IDTBT, we utilized a nanowire template printing process. This approach successfully optimized the aggregation of polymer chains during film formation and enabled the precise transfer of the nanowire thin film onto target substrates, significantly enhancing the transistor performance of the IDTBT organic film. The heterojunction synaptic devices constructed based on this method also exhibited substantially optimized electrical properties. Under the mechanism of optoelectronic synergy, these devices successfully emulated the learning-forgetting processes and image-sensing functions of the human brain, demonstrating significant potential for future artificial vision systems.
