Morphological and Structural Evolution of Chemically Deposited Epitaxially LaNiO<sub>3</sub> Thin Films

We report the preparation and characterization of epitaxial LaNiO<sub>3</sub> (LNO) thin films by chemical solution deposition method using lanthanum and nickel acetylacetonates as starting reagents dissolved in propionic acid. In order to obtain further information regarding the decompo...
