Physics of Carbon Nanotubes
The fundamental relations governing the geometry of carbon nanotubes are reviewed, and explicit examples are presented. A framework is given for the symmetry properties of carbon nanotubes for both symmorphic and non-symmorphic tubules which have screw-axis symmetry. The implications of symmetry on the vibrational and electronic structure of ID carbon nanotube systems are considered. The corres...
متن کاملOptical and Vibrational Properties of Boron Nitride Nanotubes
As for carbon nanotubes, optical and vibrational spectroscopy in particular Raman and luminescence spectroscopy play an important role for the characterization of BN nanotubes. In this chapter we review, from a theoretical view point, the different spectroscopic techniques that are currently used for BN-nanotubes and make a close link with available experimental data. We summarize experimental ...
متن کاملVibrational Excitation in Electron Transport through Carbon Nanotube Quantum Dots.
Electron transport in single-walled carbon nanotubes (SWCNTs) is extremely sensitive to environmental effects. SWCNTs experiencing an inhomogeneous environment are effectively subjected to a disorder potential, which can lead to localized electronic states. An important element of the physical picture of such states localized on the nanometer-scale is the existence of a local vibronic mainfold ...
متن کاملRaman Scattering in Carbon Nanotubes
The vibrational properties of single-walled carbon nanotubes reflect the electron and phonon confinement as well as the cylindrical geometry of the tubes. Raman scattering is one of the prime techniques for studying the fundamental properties of carbon tubes and nanotube characterization. The most important phonon for sample characterization is the radial-breathing mode, an in-phase radial move...
متن کاملEnergy dispersion in graphene and carbon nanotubes and molecular encapsulation in nanotubes
Density-functional calculations of electronic and vibrational dispersion energies for pristine graphite monolayer graphene and single-walled carbon nanotubes SWCNTs are presented. Optimized parameters for nonlocal norm-preserving pseudopotentials which replace the potential field due to core electrons are given. Comparison with observations, where available, is made. The effect of encapsulation...
