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…
Measuring the intrinsic charge transfer gap using K-edge X-ray absorption spectroscopy
C. Gougoussis, M. Calandra, A. Seitsonen +3
Pre-edge features in X-ray absorption spectroscopy contain key information about the lowest excited states and thus on the most interesting physical properties of the system. In tr…
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…
