Energetics, structure, mechanical and vibrational properties of single-walled carbon nanotubes

In this paper, we present extensive molecular mechanics and molecular dynamics studies on the energy, structure, mechanical and vibrational properties of single-wall carbon nanotubes. In our study we employed an accurate interaction potential derived from quantum mechanics. We explored the stability domains of circular and collapsed cross section structures of armchair (n,n), zigzag (n, 0), and...

Electronic Properties of Single-Walled Carbon Nanotubes

This communication describes scanning tunnelling microscopy investigations of the electronic properties of singlewalled carbon nanotubes (SWNTs). First, the unique relationship between the atomic structure and electronic properties of SWNTs is presented. Second, structural defects in nanotubes are addressed, and quantum size effects in SWNTs are discussed. Lastly, the effects of magnetic impuri...

Nanoscale Vibrational Analysis of Single-walled Carbon Nanotubes

LLE Review, Volume 100 269 Introduction Since their discovery in the early 1990s by Iijima,1 carbon nanotubes have become the focus of intense interest by a vast number of scientists and engineers. The main reason behind such wide-ranging attention lies in their unique electrical,2 mechanical,3 thermal,3 and optical properties.4 Furthermore, from their size and structure, carbon nanotubes provi...

Nanoscale vibrational analysis of single-walled carbon nanotubes.

We use near-field Raman imaging and spectroscopy to study localized vibrational modes along individual, single-walled carbon nanotubes (SWNTs) with a spatial resolution of 10-20 nm. Our approach relies on the enhanced field near a laser-irradiated gold tip which acts as the Raman excitation source. We find that for arc-discharge SWNTs, both the radial breathing mode (RBM) and intermediate frequ...

Internal resonance of vibrational modes in single-walled carbon nanotubes

We show, by molecular dynamics simulations, that 2 : 1 internal resonance may occur between a radial breathing mode (RBM) and a circumferential flexural mode (CFM) in single-walled carbon nanotubes (SWCNTs). When the RBM vibration amplitude is greater than a critical value, automatic transformations between the RBM and CFM with approximately half RBM-frequency are observed. This discovery in th...
