title: Superconductivity of monolayer Mo2C: The key role of functional groups.
abstract: Monolayer Mo2C is a new member of two-dimensional materials. Here the electronic structure and lattice dynamics of monolayer Mo2C are calculated. According to the electron-phonon interaction, it is predicted that monolayer Mo2C could be a quasi-two-dimensional superconductor and the effects of functional-groups are crucially important considering its unsaturated surface. Despite the suppressed superconductivity by chalcogen adsorption, our most interesting prediction is that the electron-phonon interaction of monolayer Mo2C can be greatly enhanced by bromine absorption, suggesting that Mo2CBr2as a good candidate for a nanoscale superconductor.
