The stretching modes at the Brillouin-zone center are remarkably softened by the electron-doping, which results in the strong electron-phonon coupling. The superconductivity can be introduced by a doped electron density above , and may exist over the liquid-helium temperature when . The superconductivity can be significantly tuned and enhanced by applying tensile strain. The… Expand
