Structural evolution and phase diagram of the superconducting iron selenides $mathrm{L}{mathrm{i}}_{x}{({mathrm{C}}_{2}{mathrm{H}}_{8}{mathrm{N}}_{2})}_{y}mathrm{F}{mathrm{e}}_{2}mathrm{S}{mathrm{e}}_{2}(x=0∼0.8)$

Author(s): Linlin Zhao, Da Wang, Qingzhen Huang, Hui Wu, Ruijin Sun, Xiao Fan, Yanpeng Song, Shifeng Jin, and Xiaolong ChenHere we report on the structural and electronic phase diagram of lithium and ethylenediamine intercalated FeSe in a wide range of dopant concentration (x=0∼0.8). Undoped (C2H8N2)yFe2Se2 crystallizes in an orthorhombic phase. With increasing lithium doping, an orthorhombic to tetragonal phase transit…[Phys. Rev. B 99, 094503] Published Mon Mar 04, 2019
