Abstract

The microstructures of SmFeAs(O,F), Ba(Fe,Co)₂As₂, and FeTe_0.5Se_0.5 prepared on CaF₂ substrates were investigated using transmission electron microscopy. The SmFeAs(O,F)/CaF₂ interface is steep, without a disordered layer. By contrast, a chemical reaction occurs at the interface in the cases of Ba(Fe,Co)₂As₂ and FeTe_0.5Se_0.5. The reaction layers are located on opposite sides of the interface for Ba(Fe,Co)₂As₂ and FeTe_0.5Se_0.5. We found that the lattice distortion of the three superconducting films on the CaF₂ substrates enhances the T_C values compared with films prepared on oxide substrates. The origin of this lattice deformation varies depending on the superconducting material.
