A photonic synaptic transistor with CNFs can perform fundamental functions, including short-term plasticity, long-term plasticity, spike-number-dependent, and spike-time-dependent plasticity, to mimic sensing, computing, and memory functions. Notably, a synaptic device with CNFs presents an ultralow energy consumption of 0.18 fJ and zero-gate operation. The superior performance of synaptic devices with CNFs can be attributed to two factors: (i) homogeneous axial distribution of the QDs and (ii) the formation of P3HT nanofibrils and co-aggregates. Therefore, enhanced interfacial charge transfer between QDs and P3HT, ensuring decent carrier transport capability, is achieved. Collectively, the composite artificial synapse successfully provides an effective guide that offers a new perspective for the fabrication of one-dimensional self-assembled nanostructure-based artificial synapses emulating human-like memory, neuromorphic computing, and artificial intelligent systems. ? 2021 Wiley-VCH GmbH |
