چکیده

We calculated the linewidths due to electron—phonon coupling of the acoustic phonon modes in NbC within a first-principles linear-response scheme. We find a pronounced correlation between anomalies in the phonon frequencies and the corresponding phonon linewidths originating from details of the Fermi surface. ( 1999 Elsevier Science B.V.

Phonon linewidths and electron-phonon coupling in graphite and nanotubes

We show 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 the optical-phonon EPCs from the G and G− linewidths. The experimental EPCs compare extremely well with those from the density functional theory. We show that the EPC explains the difference in the Raman spectra of metall...

نقش دینامیک شبکه در ابررسانای La2-xBaxCuO4 به روش DFT

Electron-phonon coupling parameters are calculated for La2-x BaxCuO4 cuprate superconductor in a wide range of dopings, from undoped to overdoped compounds. In this study we aim to study the quality of such calculations based on DFT method so, the results of σ GGA+U electronic structure calculations are also investigated. The obtained value for electron-phonon coupling is in the same order of p...

Electronic-structure dependence of the electron-phonon interaction in Ag.

The linewidths of sp- and d-band derived electronic quantum-well states in thin films of Ag on Fe(100) are measured as a function of temperature to yield the electron-phonon coupling parameters. The results vary by a factor of up to 35 among the different states. The origin of these huge differences is traced to the decay path selection for the various initial states of the holes created by the...

Origin of Strong Coupling in Lithium under Pressure

In an attempt to provide a clearer understanding of the impressive increase in Tc under pressure in elemental Li, linear response calculation of the phonon dispersion curves, electron-phonon matrix elements, phonon linewidths and mode λ’s have been carried out on a finer mesh (24 in the Brillouin zone) than done previously, for the volume corresponding to 20 GPa pressure. The result illustrates...

A model Hamiltonian for MgB2 which takes into account its unusual phononic features.

A model Hamiltonian for MgB 2 which takes into account its unusual phononic features. Abstract Taking as a starting point the results of LDA calculations, which show that in M gB 2 the phonons have a strong quartic anharmonicity and that the bond-stretching electron-phonon interaction (EPI) has both a linear and a large quadratic component, we propose a model Hamiltonian which succesfully match...
