Abstract

$\ensuremath{\alpha}\text{-FeSe}$ with the PbO structure is a key member of the family of high-${T}_{c}$ iron pnictide and chalcogenide superconductors, as while it possesses the basic layered structural motif of edge-sharing distorted ${\text{FeSe}}_{4}$ tetrahedra, it lacks interleaved ion spacers...
