Abstract

An optoelectronic artificial synapse device has been established based on ZnO/Zn-HQ nanoporous hybrid thin films by atomic/molecular layer deposition. This unique nanoporous microstructure in devices significantly enhances the optoelectronic response and relaxation time, enabling important biosynaptic functions under optical stimuli, such as Pavlov’s dog experiment and pattern recognition. The mechanism of ionization–deionization of oxygen vacancies has been proposed for this device.

基于ZnO/纳米孔杂化薄膜的光电人工突触的原子/分子层沉积

以ZnO/Zn-HQ纳米多孔杂化薄膜为材料，采用原子/分子层沉积方法制备了一种光电人工突触器件。这种独特的纳米孔结构显著增强了器件的光电响应和弛豫时间，使重要的生物突触功能在光学刺激下得以实现，如巴甫洛夫狗实验和模式识别。提出了该装置氧空位的电离-去电离机理。

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
