Dynamic friction force in a carbon peapod oscillator

  title={Dynamic friction force in a carbon peapod oscillator},
  author={Haibin Su and William A. Goddard and Yang Zhao},
We investigate a new generation of fullerene nano-oscillators: a single-walled carbon nanotube with one buckyball inside with an operating frequency in the tens-of-gigahertz range. A quantitative characterization of energy dissipation channels in the peapod pair has been performed via molecular dynamics simulation. Edge effects are found to be the dominant cause of dynamic friction in the carbon-peapod oscillators. A comparative study on the energy dissipation also reveals the significant… 
An ion-charged carbon nanotube oscillator beyond the terahertz regime
A frequency-tunable nano-oscillator consisting of a K+ ion and a negatively-charged carbon nanotube (CNT) was proposed. The ion induces a strong dielectric response on the wall of the CNT, which can
An oscillator in a carbon peapod controllable by an external electric field: a molecular dynamics study.
We investigate the peapod structure of C(59)N(+)@(10, 10) single-walled carbon nanotubes by simulation, and discover that the ball initial velocity could be controlled by the external impulse
Atomic-resolution three-dimensional force and damping maps of carbon nanotube peapods.
The damping energy DeltaE signals, generated in very close proximity of the tip and nanotube peapod, show a close relationship with hysteresis in the short-range forces, thereby indicating that a soft vibrational (phonon) mode is site-specifically induced by the AFM tip.
In this study, a novel semi-analytical approach is presented to evaluate the preferred position of an offset inner single-walled carbon nanotube (SWCNT) with reference to the cross-section of outer
Atomically resolved mechanical response of individual metallofullerene molecules confined inside carbon nanotubes.
The hollow core inside a carbon nanotube can be used to confine single molecules and it is now possible to image the movement of such molecules inside nanotubes. To date, however, it has not been
Transport of fullerene molecules along graphene nanoribbons
The results suggest that both electorphoresis and thermophoresis can be employed to control the motion of carbon molecules and fullerenes, such that larger and more asymmetric structures demonstrate much lower mobility.
Dimensionless Analysis of Carbon Nanotube Oscillators: Design Aspects
AbstractIn the past decade, gigahertz nano-oscillators have attracted much attention. Of particular interest are nested carbon nanotubes with telescopic movements. Recent work on this type of
Simulations on the effects of confinement and Ni-catalysis on the formation of tubular fullerene structures from peapod precursors
We applied the recently developed reactive force field ReaxFF to study the dynamics of tubular fullerene formation process starting from C60-buckyball/nanotube peapod structures. We found that the


Dynamic sliding friction between concentric carbon nanotubes.
It is suggested that a strong velocity dependence and strong contributions from surface edges may be quite general features of friction at the nanoscale.
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

We reported in a previous study (Zhao et al 2003 Phys. Rev. Lett. 91 175504) that energy transfer from the orderly intertube translational oscillation to intratube vibrational modes for an isolated

The results show that these nano-oscillators are dynamically stable when the radii difference values between inner and outer tubes are of approximately 3.4 A.
Quantum conductance of carbon nanotube peapods
We present a first-principles study of the quantum conductance of hybrid nanotube systems consisting of single-walled carbon nanotubes (SWCNTs) encapsulating either an isolated single C60 molecule or
Low-friction nanoscale linear bearing realized from multiwall carbon nanotubes
The controlled and reversible telescopic extension of multiwall carbon nanotubes is demonstrated, thus realizing ultralow-friction nanoscale linear bearings and constant-force nanosprings and near perfect, wear-free surfaces.
Multiwalled carbon nanotubes as gigahertz oscillators.
The retraction energy of a multiwalled carbon nanotube with an extruded core causes the core to oscillate with respect to its fully retracted position where the van der Waals potential energy is minimized, resulting in nanomechanical systems of operating frequency up to several gigahertz.
Nanomechanical resonance studies of carbon nanotube peapod bundles
Filled carbon nanotubes represent a class of tunable nanoscale materials that could provide both high-quality resonance and sensing specificity for nanoresonator-based devices. We have studied the
