La0.6Ca0.4CoO3 (LCCO) thin films were deposited on MgO(001) and stainless steel substrates by pulsed reactive crossed-beam laser ablation (PRCLA). The film stoichiometry was characterized by Rutherford backscattering spectrometry (RBS). The data confirmed that the material transfer from the target to the substrate is congruent. The thickness and surface roughness of the films is in the range of 200–500 and 2–12 nm, respectively, depending on the deposition conditions. The quality of the deposited film was analyzed by X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). Epitaxial and single oriented thin films could be grown. In view of the importance of the surface composition in electrochemistry, X-ray photoelectron spectroscopy (XPS) measurements were performed. The electrochemical activity of the LCCO films is influenced by the crystallinity of the film.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
