本文从理论上研究了一种新型的基于碳纳米管的双极纳米继电器,它是一种能够在强核辐射下工作的纳米机电开关,并分析了其工作过程中“拉入“、“连接“和“拉回“等工作阶段的物理机制以及影响器件效率的关键因素。我们明确地提供了两个重要的工作电压,V拉入和V拉回的解析表达式,从而清楚地显示了本器件的材料特性和几何形状的依赖关系,从基本物理的分析方法,避免了复杂的数值计算。我们的方法是很容易使用的,在制备本装置和其他纳米机电装置的设计指南。
We theoretically investigate a novel and powerful double-pole nanoscale relay based on a carbon nanotube, which is one of the nanoelectromechanical switches being able to work under the strong nuclear radiation, and analyze the physical mechanism of the operating stages in the operation, including “ pull in, ” “ connection, ” and “ pull back, ” as well as the key factors influencing the efficiency of the devices. We explicitly provide the analytical expression of the two important operation voltages, V pull in and V pull back , therefore clearly showing the dependence of the material properties and geometry of the present devices by the analytical method from basic physics, avoiding complex numerical calculations. Our method is easy to use in preparing the design guide for fabricating the present device and other nanoelectromechanical devices.
