An organic synaptic transistor (OST) that utilizes a multiple‐annealing process and an ion gate to achieve significant reductions in operating voltage and increases in transconductance is demonstrated. The OST exhibits an ultra‐short‐term plasticity (USTP) with a maximum retention time of only 20.7 ms, which does not increase with the number and duration of spikes. This is the shortest retention time yet achieved by an ion‐gel‐regulated synaptic transistor. In addition, OST‐integrated array exhibits a tunable weight plasticity and a short weight refresh time for a stable image resetting in ample time of <0.2 s. It is also sensitive to the frequency and amplitude of electrical inputs; a low‐frequency suppression and a nonlinear amplitude gain enables OST‐constructed filter for use in processing multiple types of signals. This work is a step toward constructing high‐performance and multifunctional artificial intelligent systems.

具有超短期权重重建功能的有机突触晶体管可处理多种类型的信号

展示了一种有机突触晶体管（OST），它利用多次退火工艺和离子门来实现工作电压的显着降低和跨导的增加。 OST 表现出超短期可塑性 (USTP)，最大保留时间仅为 20.7 ms，并且不会随着尖峰数量和持续时间的增加而增加。这是离子凝胶调节突触晶体管迄今为止实现的最短保留时间。此外，OST集成阵列表现出可调的权重可塑性和短的权重刷新时间，可在<0.2 s的充足时间内实现稳定的图像重置。它还对电输入的频率和幅度敏感；低频抑制和非线性幅度增益使得 OST 构造的滤波器能够用于处理多种类型的信号。这项工作是朝着构建高性能和多功能人工智能系统迈出的一步。
