共混诱导制备圆偏振光突触晶体管
Preparation of circularly polarized synaptic transistor by blending induction
摘要
Abstract
Photonic artificial synapse(PAS)devices with the functions of circularly polarized light(CPL)recognition and memory learning are of great value to advanced neuromorphological vision systems.In this study,CPL synaptic transistor devices in the visible range are fabricated by simple blending strategy and multilayer structure design.Experiments show that films prepared by blending chiral small molecules benzoic acid,4-[[4-(hexyloxy)benzoyl]oxy]-,1,1′-[1,1′-binaphthalene]-2,2′-diyl ester(S6N)or benzoic acid,4-(hexyloxy)-,[1,1′-binaphthalene]-2,2′-diylbis(oxycarbonyl-4,1-phenylene)ester,(R)-(9CI)(R6N)with poly(9,9-dioctylfluorene-2,7-diyl)(PFO)had strong chiral optical activity after annealing induction.Using the blend film as the chiral layer and the dithiophene-azaindigo-nitrogen-containing benzodifurandione donor-acceptor conjugated polymer(C13P3.75)as the charge transport layer,the prepared double-layer phototransistor can simulate various biological synaptic behaviors under 405 nm CPL irradiation.Excitatory postsynaptic current(EPSC),paired-pulse facilitation(PPF)and the transition from short-term memory(STM)to long-term memory(LTM)were successfully simulated.The experimental results show that the device has excellent CPL discrimination ability,and the photocurrent asymmetry factor of 405 nm CPL reaches-0.492.关键词
