Epitaxial Pd-Doped LaFeO₃ Films Grown on (100) SrTiO₃ by Pulsed Laser Deposition

Abstract:

Single-crystalline, epitaxial LaFeO₃ films with 5 at. % substitution of Pd on the Fe site are grown on (100) SrTiO₃ substrate by pulsed-laser deposition technique. The epitaxial orientation relationships are (110)[001]_LFPO||(100)[001]_STO. X-ray diffraction and transmission electron microscopy reveal that the LFPO films have high structural quality and an atomically sharp LFPO/STO interface. After reduction treatments of as-grown LFPO films, very little Pd escaped the LFPO lattice onto the film surface, the formed Pd (100) particles are oriented epitaxially, and parallel to the LFPO films surface.
