Phonon-mediated superconductivity in silicene predicted by first-principles density functional calculations
We predict that electron-doped silicene is a good two-dimensional electron-phonon superconductor under biaxial tensile strain by first-principles calculations within rigid band approximation.Superconductivity transition temperature of electron-doped silicene can be increased to be above 10 K by 5% tensile strain.Band structures, phonon dispersive relations, and Eliashberg functions are calculated for detailed …
