Electron-doped phosphorene: A potential monolayer superconductor

Abstract

We predict by first-principles calculations that the electron-doped phosphorene is a potential BCS-like superconductor. 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 ($n_{2D}$) above $1.3\times 10^{14}$ cm${}^{-2}$, and may exist over the liquid helium temperature when $n_{2D}>2.6\times 10^{14}$ cm${}^{-2}$. The maximum critical temperature is predicted to be higher than 10 K. The superconductivity of phosphorene will significantly broaden the applications of this novel material.
