Molecular Dynamics Study of Tunable Double-Walled Carbon Nanotube Oscillator

초록

Telescoped double-walled carbon nanotubes for a tunable ultrahigh frequency resonator are investigated via classical molecular dynamics simulations. Increasing the length of the telescoped double-walled carbon nanotubes resulted in a reduced fundamental resonance frequency. Harmonic frequencies are also present in the oscillation of the telescoped double-walled carbon nanotubes. Fundamental frequencies analyzed via the continuum model reasonably coincide with those obtained from classical molecular dynamics simulations. However, since the inelasticity of the telescoped double-walled carbon nanotubes increases with increasing length, the fundamental frequency obtained from the classical molecular dynamics simulation differs from the calculated frequency, according to the increase in length.
