A [10, 10]/[5,5] nanotube-based oscillator is studied using molecular dynamics in this paper. The inner tube can oscillate inside the outer tube with a stable frequency of 55GHz, if this nanomechanical system is insulated. When temperature effects are considered, it is found that the nanooscillator will stop due to the temperature-related interlayer friction between the outer tube and the inner tube. A nanoelectromechanical system (NEMS) is designed by coating electrodes on the top of the outer tube. The electromagnetic forces, induced by the WRITE voltage pulses that are applied on the electrodes, can overcome the interlayer friction. The frequency of the proposed NEMS oscillator depends on the frequency of the WRITE voltage pulses.
