Deep ultraviolet (DUV)-light-stimulated artificial synaptic devices exhibit potential applications in various disciplines including intelligent military monitoring, biological and medical analysis, flame detection, etc. Along these lines, we report here a DUV-light-stimulated transistor fabricated on poly(3-hexylthiophene) (P3HT) ultrathin film that responds selectively to DUV light. Significantly, our have the ability successfully simulate synapse-like behaviors excitatory postsynaptic currents (EPSCs), paired-pulse facilitation (PPF), short-term memory (STM), long-term (LTM), STM-to-LTM transition, learning forgetting behaviors. Moreover, proposed structures were also flexible poly(ethylene terephthalate) (PET) substrates simulated typical behaviors, which could be of great importance for wearable applications.
