It is suggested that chiral photonic bio-enabled integrated thin-film electronic elements can pave the base for next-generation optoelectronic processing, including quantum coding for encryption as well as integrated multi-level logic circuits. Despite recent advances, thin-film electronics for encryption applications with large-scale reconfigurable and multi-valued logic systems are not reported to date. Herein, highly secure optoelectronic encryption logic elements are demonstrated by facilitating the humidity-sensitive helicoidal organization of chiral nematic phases of cellulose nanocrystals (CNCs) as an active electrolyte layer combined with printed organic semiconducting channels. The ionic-strength controlled tunable photonic band gap facilitates distinguishable and quantized 13-bit electric signals triggered by repetitive changes of humidity, voltage, and the polarization state of the incident light. As a proof-of-concept, the integrated circuits responding to circularly polarized light and humidity are demonstrated as unique physically unclonable functional devices with high-level logic rarely achieved. The convergence between functional nanomaterials and the multi-valued logic thin-film electronic elements can provide optoelectronic counterfeiting, imaging, and information processing with multilevel logic nodes.
有人认为，手性光子生物集成薄膜电子元件可为下一代光电处理奠定基础，包括用于加密的量子编码以及集成多级逻辑电路。尽管最近取得了进展，但迄今为止尚未报道用于具有大规模可重构和多值逻辑系统的加密应用的薄膜电子学。在此，通过促进纤维素纳米晶体（CNC）手性向列相的湿度敏感螺旋组织作为活性电解质层与印刷有机半导体通道相结合，展示了高度安全的光电加密逻辑元件。离子强度控制的可调谐光子带隙促进了由湿度、电压和入射光偏振态的重复变化触发的可区分和量化的13位电信号。作为概念验证，响应圆偏振光和湿度的集成电路被证明是具有很少实现的高级逻辑的独特物理不可克隆功能器件。功能纳米材料与多值逻辑薄膜电子元件之间的融合可为具有多级逻辑节点的光电防伪、成像和信息处理提供支持。
