A double-walled carbon nanotube (CNT) oscillator encapsulating a copper nanowire has been investigated using molecular dynamics simulations. Our simulation results show that the excess energy due to the interactions between the copper nanowire and the outer CNT were around 1% of the excess of van der Waals energy between the inner and the outer CNTs. The classical oscillation theory and the theory given by Zheng et al (2002 Phys. Rev. Lett. 88 045503) provide a fairly good estimate of the mass-dependent frequency of a CNT oscillator encapsulating a metal nanowire. The nanotube oscillator encapsulating a metal nanowire is found to be more dependent on the encapsulated metal mass than the metal-carbon interaction.
