Chemical deposition of La0.7Ca0.3MnO3±δ films on ceramic substrates

In this paper, it is reported the growth of La0.7Ca0.3MnO3±δ films using a chemical solution deposition method (CSD) by the spin-coating technique. Such solution was prepared through a route based on modified polymeric precursor method. Spin-coating deposition on different ceramic substrates was performed and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM...

Morphological and electrical evolution of ZnO: Al thin filmsdeposited by RF magnetron sputtering onto glass substrates

In this work, the surface and electrical characteristics ZnO:Al thin films deposited by RF magnetron sputtering onto glass substrates have been investigated. Analysis of surface morphologies revealed two growth stages. In the first stage, up to thicknesses of 100 nm, the films show surface structures with a granular form without preferential orientation. Beyond thicknesses of 100...
