In this paper, we first investigate mechanisms of nanotube-based co-axial oscillators, shown in Figure 1, based on molecular dynamics simulation. We mainly study the interlayer friction between the outer tube and the inner tube when the oscillators are at finite temperatures. Based on our studies, we propose to design a nanoelectromechanical oscillator system, which can be utilized as memory cells. In addition, we propose the first numerical study of nanotube-based resonant oscillators, shown in Figure 2, via a new multiscale method. Temperature effects are also investigated.
