Influence of fluorination on electronic states and electron transport properties of Sr₂IrO₄ thin films

Abstract

We fabricated layered-perovskite Sr2IrO4−xF2x thin films by combining pulsed-laser deposition with topotactic fluorination and investigated the modulation of their electronic states and electron transport properties.

Improvement of electric insulation in dielectric layered perovskite nickelate films via fluorination

“…This method of topotactic fluorination using PVDF was conducted earlier for perovskite nickel oxide films 21,22 and layered perovskite films. 23,24 The typical thicknesses of the films were 50-60 nm. The lattice constants were analyzed using X-ray diffraction (XRD) with Cu-Ka radiation.…”
