Thermal transport in isotopically disordered carbon nanotubes
Gabriel Stoltz, Michele Lazzeri, Francesco Mauri
We present a study of the phononic thermal conductivity of isotopically disordered carbon nanotubes. In particular, the behavior of the thermal conductivity as a function of the sy…
Impact of the electron-electron correlation on phonon dispersions: failure of LDA and GGA functionals in graphene and graphite
Michele Lazzeri, Claudio Attaccalite, Ludger Wirtz +1
We compute electron-phonon coupling (EPC) of selected phonon modes in graphene and graphite using various ab-initio methods. The inclusion of non-local exchange-correlation effects…
Structure, Stability, Edge States and Aromaticity of Graphene Ribbons
Tobias Wassmann, Ari P. Seitsonen, A. Marco Saitta +2
We determine the stability, the geometry, the electronic and magnetic structure of hydrogen-terminated graphene-nanoribbons edges as a function of the hydrogen content of the envir…
Temperature dependent phonon renormalization in metallic nanotubes
V. Scardaci, S. Piscanec, Michele Lazzeri +3
We measure the temperature dependence of the Raman spectra of metallic and semiconducting nanotubes. We show that the different trend in metallic tubes is due to phonon re-normaliz…
Phonon anharmonicities in graphite and graphene
Nicola Bonini, Michele Lazzeri, Nicola Marzari +1
We determine from first-principles the finite-temperature properties--linewidths, line shifts, and lifetimes--of the key vibrational modes that dominate inelastic losses in graphit…
Optical Phonons in Carbon Nanotubes: Kohn Anomalies, Peierls Distortions and Dynamic Effects
Stefano Piscanec, Michele Lazzeri, John Robertson +2
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-ph…
