Molecular Dynamics Analysis of Graphene-Based Nanoelectromechanical Switch
摘要：
在这里，我们提出了基于石墨烯的纳米机电开关与垂直的碳纳米管电极通过经典的分子动力学模拟。碳纳米管生长在方孔的中心，石墨烯覆盖在方孔上。施加孔的底部与石墨烯之间的电势差以使石墨烯偏转。通过经典分子动力学模拟，研究了石墨烯基碳纳米管纳米机电开关的机电特性，该开关可以通过外力来实现开关.这项模拟工作明确表明，这种器件适用于纳米传感器和量子计算，以及超快速响应开关器件。
英文摘要：
Here we present graphene-based nanoelectromechanical switch with the vertical carbon nanotube electrode via classical molecular dynamics simulations. The carbon nanotube is grown in the center of the square hole and the graphene covers on the hole. The potential difference between the bottom of the hole and the graphene is applied to deflect the graphene. By performing classical molecular dynamic simulations, we investigate the electromechanical properties of graphene-based nanoelectro- mechanical switch with carbon nanotube electrode, which can be switched by the externally applied force. This simulation work explicitly demonstrated that such devices are applicable to nanoscale sensors and quantum computing, as well as ultra-fast-response switching devices.
