Phonon Linewidths and Electron Phonon Coupling in Nanotubes
Michele Lazzeri, S. Piscanec, Francesco Mauri +2
We prove that Electron-phonon coupling (EPC) is the major source of broadening for the Raman G and G- peaks in graphite and metallic nanotubes. This allows us to directly measure t…
Superconductivity in C6Ca
Matteo Calandra, Francesco Mauri
Using density functional theory we demonstrate that superconductivity in C6Ca is due to a phonon-mediated mechanism with electron-phonon coupling 0.83 and phonon-frequency logarith…
Electronic-enthalpy functional for finite systems under pressure
Matteo Cococcioni, Francesco Mauri, Gerbrand Ceder +1
We introduce the notion of electronic enthalpy for first-principles structural and dynamical calculations of finite systems under pressure. An external pressure field is allowed to…
Electron Transport and Hot Phonons in Carbon Nanotubes
M. Lazzeri, S. Piscanec, F. Mauri +2
We demonstrate the key role of phonon occupation in limiting the high-field ballistic transport in metallic carbon nanotubes. In particular, we provide a simple analytic formula fo…
Localized-orbital computation of linear and nonlinear susceptibilities
Andrea Dal Corso, Francesco Mauri
We present a method to compute high-order derivatives of the total energy which can be used in the framework of density functional theory. We provide a proof of the theorem…
