Energy dissipation mechanisms in carbon nanotube oscillators
Energy transfer from the translational degrees of freedom to phonon modes is studied for isolated systems of two coaxial carbon nanotubes, which may serve as a nearly frictionless nano-oscillator. It is found that for ...
Energy exchanges in carbon nanotube oscillators
Energy exchanges between orderly intertube axial motion and vibrational modes are studied for isolated systems of two coaxial carbon nanotubes at temperatures ranging from 300 to 500 K. It is found that the excess ...
A tribological study of double-walled and triple-walled carbon nanotube oscillators
We reported in a previous study that energy transfer from the orderly intertube translational oscillation to intratube vibrational modes for an isolated system of two coaxial carbon nanotubes at low temperatures ...
Trans-phonon effects in ultra-fast nanodevices
We report a novel phenomenon in carbon nanotube based ultra-fast mechanical devices, the trans-phonon effect, which resembles the transonic effects in aerodynamics. It is caused by dissipative resonance of nanotube phonons ...
Quasi-reversible energy flows in carbon-nanotube oscillators
Quasi-reversible energy flows between orderly intertube axial motion and vibrational modes are studied for isolated systems of two coaxial carbon nanotubes at temperatures ranging from 300 K to 500 K. It is found that the ...
