基于碳纳米管的纳机电系统的可控稳定振动
Controlled Stable Oscillations of Carbon Nanotube-based NEMS
摘要
Abstract
A numerical method was used to investigate the conditions to sustain the stable motion of nanoelectromechanical systems (NEMS) based on carbon nanotubes under periodical harmonic driving force.We determined the parameters of the system and control force which allow obtaining the sustained stable oscillation at a constant frequency.The operating characteristics of the double-walled carbon nanotube oscillators were calculated and analyzed.It is shown that the sustained stable motion of the oscillators can be realized by properly choosing the amplitude and the initial phase of the periodical harmonic driving force.The method reported here is believed to have important implications in carbon nanotube-based NEMS design.关键词
