摘要 纳米开关结构是纳米机电系统以及未来纳米计算机、纳米机器人的重要控制元件,它具有体积小、重量轻、功耗低、谐振频率高、响应时间短等优点,在亚微米器件中有着潜在的应用前景。随着纳米开关结构尺寸的减小,材料最外层表面原子所占的比例大幅度增加,比表面积、比表面能也迅速增加,呈现出显著的尺寸相关性,其物理、化学、力学性能与宏观物体有所不同。本文对纳米机械开关结构的力学行为研究现状进行了评述,集中讨论了纳米机械开关的典型力学行为研究,涉及各种边界条件下纳米机械开关结构受电、机载荷作用的情况,并提出需要进一步研究的方向。 Nano-switches are the fundamental building blocks of nano devices such as nano-electromechanical system(NEMS), nano-computers and nano-robots. For the advantages of small volume, light weight, low power consumption, high resonant frequency and short response time, nano-switches are now developed for general use as structural components in micro nano devices. Owing to the greatly increasing ratio of surface area to volume,their physical, chemical and mechanical properties display evident size dependence, which are clearly distinct from their macroscopic counterparts. This article reviews recent investigation concerning the responses of nano-switches. Future research needs are highlighted.
