Description
The influence of annealing time on microstructure, morphological, electrical and mechanical properties of La1.9Ce0.1CuO4 (LCCO) superconducting films has been studied. Single-phase LCCO thin films were prepared by pulsed-laser deposition on SrTiO3 substrate with varying annealing time. Microstructure and morphology of the LCCO films were investigated using x-ray diffraction and atomic force microscopy. Temperature dependence of electrical resistance of the LCCO films was determined by four-point method. Hardness and elastic modulus of the LCCO films were characterized by depth sensing nanoindentation technique. Results show that annealing time mainly affects the hardness and elastic modulus of the LCCO films through Cu-rich particles and the crystallite size. However, the influence of Cu-rich particles is much less remarkable than that of the crystallite size. (paper)
