The superconductivity and electron-doping effect in MgP₂H₁₄ hydrides.

ABSTRACT: Room temperature superconductivity has become the tireless pursuit of scientists due to its epoch-making significance. Inspired by the recently predicted high superconductivity in LiP₂H₁₄, we identify a new superconductor MgP₂H₁₄ by substituting Li with Mg and prove its stability. The superconducting critical temperature (T _c) and electron-phonon coupling (EPC) parameters (λ) of MgP₂H₁₄ under 280 GPa are predicted to be ∼166 K and ∼1.65, respectively; the high superconductivity of MgP₂H₁₄ mainly arises from the strong electron-phonon interaction between H 1s electrons and the H-associated vibration. Furthermore, in hydrogen-based superconductors, the hydrogen sublattice w
