Raman 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 کاملRaman Scattering of Carbon Nanotubes
The present state of Raman scattering from carbon nanotubes is reviewed. In the first part of the presentation the basic concepts of Raman scattering are elucidated with particular emphasis on resonance scattering. The classical and the quantum-mechanical description are presented and the basic experimental instrumentation and procedures are described. Special Raman techniques are discussed. Ev...
متن کاملRaman scattering in carbon nanotubes revisited
We explain the origin of the high-energy mode in the first-order Raman spectra of single-walled carbon nanotubes by double-resonant scattering. Following this interpretation, we calculate the multiple-peak structure as found in Raman experiments. The highest peak is above the graphite G-point frequency; its amplitude is larger than that of the second peak. We derive positive and negative freque...
متن کاملRaman Scattering in Carbon Nanosystems: Solving Polyacetylene
Polyacetylene has been a paradigm conjugated organic conductor since well before other conjugated carbon systems such as nanotubes and graphene became front and center. It is widely acknowledged that Raman spectroscopy of these systems is extremely important to characterize them and understand their internal quantum behavior. Here we show, for the first time, what information the Raman spectrum...
متن کاملRaman scattering from boron-substituted carbon films.
Raman scattering studies of B xC12x films have been carried out for boron concentrations in the range 0<x<0.17. The spectra exhibit two broad bands, a graphitic mode (G) centered between 1535 and 1590 cm and a disorder-induced mode ~D! centered between 1345 and 1370 cm. The G mode is observed to soften as a result of boron substitution, and this behavior has been explained using a simple two-di...
