| dc.description | The electron-phonon coupling of LaO$_{1-x}$F$_x$FeAs is re-investigated on the basis of density functional theory in local density approximation. The implications of the $(π,π)$ nesting of the Fermi surfaces are carefully studied and found to lead to a non-standard electron-phonon coupling of the corresponding Fe in-plane breathing mode, which might make a strong contribution to the high superconducting transition temperature. The semi-metallic behavior of the undoped material is also further illuminated. | |
