摘要
物理瞬态电子是指电子器件或系统在完成指定的工作任务后,在外界刺激或相关程序的启动下,通过化学或物理过程能够实现其物理形态和器件功能部分或完全消失的一种新型电子器件,它可以有效避免传统芯片中信息泄露的风险,对于确保数据安全具有非常重要的意义。除此之外,瞬态电子器件还可以减小废弃的电子产品对自然环境的污染,同时还可以应用到可植入/可穿戴式医疗电子等领域。另一方面,阻变存储器因具有结构简单、功耗低、读写速度快等优势在下一代高密度存储技术方面具有广泛的应用前景。因此,将物理瞬态电子与阻变存储器结合,对于实现信息安全存储、绿色电子等具有重要的意义。从物理瞬态阻变材料、器件大面积制备技术、多功能瞬态阻变器件及其在随机计算方面的应用介绍物理瞬态阻变存储器的研究,特别是本课题组相关进展,并对目前存在的问题进行总结以及对未来的发展进行展望。
Physical transient electronics is a new type of electronic devices or systems,which can physically disappear partially or completely after completing the specific functions in a controlled manner.Physically transient electronics have great potential in data security applications,green electronics and novel bio-integrated or bio-implantable electronics.On the other hand,resistive switching devices have great potential in the next generation of high-density storage technology due to their advantages such as simple structure,low power consumption and fast operation speed.Therefore,the combination of physically transient electronics and resistive switching devices would open new avenues for data security,green electronics as well as new bio-integrated applications.In this paper,recent progress of physically transient resistive switching memory especially in our group is summarized from the aspects of physically materials,large-area fabrication technologies,transient resistive switching devices and their application in stochastic computing.Additionally,we provide insights into the future development of resistive switching devices for data storage and transmission security applications.
