Interactions and superconductivity in heavily doped MoS2

AuthorsRoldán, Rafael ; Cappelluti, E. ; Guinea, F.
Issue Date2013
PublisherAmerican Physical Society
CitationPhysical Review B 88: 054515 (2013)
AbstractWe analyze the microscopic origin and the physical properties of the superconducting phase recently observed in MoS2. We show how the combination of the valley structure of the conduction band, the density dependence of the screening of the long-range Coulomb interactions, the short-range electronic repulsion, and the relative weakness of the electron-phonon interactions makes possible the existence of a phase where the superconducting order parameter has opposite signs in different valleys, resembling the superconductivity found in the pnictides and cuprates. © 2013 American Physical Society.
