Exciton-phonon effects in carbon nanotube optical absorption
Vasili Perebeinos, J. Tersoff, Phaedon Avouris
We find that the optical properties of carbon nanotubes reflect remarkably strong effects of exciton-phonon coupling. Tight-binding calculations show that a significant fraction of…
Electron-phonon effects and transport in carbon nanotubes
Vasili Perebeinos, J. Tersoff, Phaedon Avouris
We calculate the electron-phonon scattering and binding in semiconducting carbon nanotubes, within a tight binding model. The mobility is derived using a multi-band Boltzmann treat…
Electronic structure of S-C6H5 self-assembled monolayers on Cu(111) and Au(111) substrates
Vasili Perebeinos, Marshall Newton
We use first principles density functional theory to calculate the electronic structure of the phenylthiolate (S-CH) self-assembled monolayer (SAM) on Cu(111) and Au(111) s…
Scaling of excitons in carbon nanotubes
Vasili Perebeinos, J. Tersoff, Phaedon Avouris
Light emission from carbon nanotubes is expected to be dominated by excitonic recombination. Here we calculate the properties of excitons in nanotubes embedded in a dielectric, for…
