Low-voltage (1.5 V) indium zinc oxide (IZO)-based electric-double-layer (EDL) thin-film transistors (TFTs) gated by nanogranular proton conducting SiO2 electrolyte films are fabricated on paper substrates. Both enhancement-mode and depletion-mode operation are obtained by tuning the thickness of the IZO channel layer. Furthermore, such flexible IZO protonic/electronic hybrid EDL TFTs can be used as artificial synapses, and synaptic stimulation response and short-term synaptic plasticity function are demonstrated. The protonic/electronic hybrid EDL TFTs on paper substrates proposed here are promising for low-power flexible paper electronics, artificial synapses and bioelectronics.
基于低压（1.5 V）的铟锌氧化物（IZO）的电双层（EDL）薄膜晶体管（TFT），采用纳米颗粒质子导电 SiO2 电解质薄膜作为栅极，被制备在纸张衬底上。通过调整 IZO 沟道层的厚度，可以获得增强型和耗尽型两种工作模式。此外，这种柔性的 IZO 质子/电子混合 EDL TFT 可以用作人工突触，并展示了突触刺激响应和短期突触可塑性功能。本文提出的基于纸张衬底的质子/电子混合 EDL TFT 有望应用于低功耗柔性纸张电子、人工突触和生物电子领域。
