摘要：Crystal structures of silane have been extensively investigated using ab initio evolutionary simulation methods at high pressures. Two metallic structures with P 21/ c and C 2/ m symmetries are found stable above 383 GPa. The superconductivities of metallic phases are fully explored under BCS theory, including the reported C 2/ c one. Perturbative linear-response calculations for C 2/ m silane at 610 GPa reveal a high superconducting critical temperature that beyond the order of 102 K.
