Green With single-crystal x-ray diffraction studies, we compare the structures of three samples showing optimal superconductivity: K_{0.775(4)} Fe_{1.613(1)} Se_{2} , K_{0.737(6)} Fe_{1.631(3)} Se_{2} , and Cs_{0.748(2)} Fe_{1.626(1)} Se_{2} . All have an almost identical ordered vacancy structure with a ... [Phys. Rev. B 83, 132509] Published Mon Apr 25, 2011
