Doping and phonon renormalization in carbon nanotubes.
We show that the Raman frequency associated with the vibrational mode at approximately 1,580 cm(-1) (the G mode) in both metallic and semiconducting carbon nanotubes shifts in response to changes in the charge density induced by an external gate field. These changes in the Raman spectra provide us with a powerful tool for probing local doping in carbon nanotubes in electronic device structures,...
متن کاملOptical phonons in carbon nanotubes: Kohn anomalies, Peierls distortions, and dynamic effects
We present a detailed study of the vibrational properties of single wall carbon nanotubes SWNTs . The phonon dispersions of SWNTs are strongly shaped by the effects of electron-phonon coupling. We analyze the separate contributions of curvature and confinement. Confinement plays a major role in modifying SWNT phonons and is often more relevant than curvature. Due to their one-dimensional charac...
متن کاملOrigin of the Breit-Wigner-Fano lineshape of the tangential G-band feature of metallic carbon nanotubes
A detailed line-shape analysis of the tangential G-band feature attributable to metallic single-walled carbon nanotubes is presented. Only two components are needed to account for the entire G-band feature for metallic nanotubes. The higher-frequency component has a Lorentzian line shape, and the lower one has a BreitWigner-Fano ~BWF! line shape. Through comparisons of the Raman tangential G-ba...
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 کاملPhonon populations and electrical power dissipation in carbon nanotube transistors.
Carbon nanotubes and graphene are candidate materials for nanoscale electronic devices. Both materials show weak acoustic phonon scattering and long mean free paths for low-energy charge carriers. However, high-energy carriers couple strongly to optical phonons, which leads to current saturation and the generation of hot phonons. A non-equilibrium phonon distribution has been invoked to explain...
