Carbon molecules oscillating in carbon nanotube

Conference Paper


Abstract


  • Fullerenes C60 and carbon nanotubes are of

    considerable interest to researchers from many scientific areas

    due to their unique electronic and mechanical properties. One

    application of these carbon nanostructures that has recently

    attracted much attention is the creation of an oscillator that

    operates in the gigahertz range frequency. A number of studies

    have found that the sliding of the inner-shell inside the outershell

    of a multi-walled carbon nanotube can generate gigahertz

    oscillatory frequencies. In this paper, we investigate the

    mechanics of a gigahertz oscillator comprising a carbon nanotube

    oscillating within the centre of a uniform concentric ring or

    bundle of carbon nanotubes. Since much higher frequencies can

    be generated from a C60 fullerene oscillating inside a nanotube,

    we also consider the case of a C60 fullerene oscillating within a

    bundle of carbon nanotubes. Using the Lennard-Jones potential

    and the continuum approach, we obtain a relation between the

    bundle radius and the radii of the nanotubes forming the bundle,

    as well as the optimum bundle size which gives rise to the

    maximum oscillatory frequency for both the C60 and the

    nanotube bundle oscillators. While previous studies in this area

    have been undertaken through molecular dynamics simulations,

    this paper emphasizes the use of applied mathematical modelling

    techniques which provides considerable insight into the

    underlying mechanisms. The paper presents a synopsis of the

    major results derived in detail by the present authors in [1, 2].
