Structural evolution and phase diagram of the superconducting iron selenides Li x (C2H8N2) y Fe2Se2(x= 0 ~ 0.8)
{{output}}
Here 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 ( C 2 H 8 N 2 ) y Fe 2 Se 2 crystallizes in an orthorhombic phase. With... ...
