Abstract

The energy dissipation of the cantilever-type beam oscillators of single wall and double-walled carbon nanotubes (CNT) was investigated by applying classical molecular dynamics. It was observed that the Q factor of the CNT beam oscillator varied with the temperature. It was also observed that for single wall CNT, the Q factor dropped from 2×105 to 1.5×10 3 at 293 K. It was found that the weak interlayer binding strength and the interlayer commensurance increased the energy dissipation in the double-walled CNT oscillator.
