Organometal halide perovskite synaptic devices are fabricated; they emulate important working principles of a biological synapse, including excitatory postsynaptic current, paired-pulse facilitation, short-term plasticity, long-term plasticity, and spike-timing dependent plasticity. These properties originate from possible ion migration in the ion-rich perovskite matrix. This work has extensive applicability and practical significance in neuromorphic electronics.
制备了金属有机卤化物钙钛矿突触器件;它们模拟了生物突触的重要工作原理,包括兴奋性突触后电流、成对脉冲易化、短期可塑性、长期可塑性和尖峰时间依赖可塑性。这些特性源于富含离子的钙钛矿基质中可能的离子迁移。这项工作在神经形态电子学中有广泛的适用性和实际意义。
