摘要: Metal-intercalated iron selenides are a class of superconductors that have received much attention but less understood in comparison with their FeAs-based counterparts. Here, the controversial issues such as Fe vacancy, the real phase responsible for superconductivity and lattice stability have been addressed based on first-principles calculations. New insights on the distinct features in terms of carrier doping have been revealed.
