Abstract

Pr2Ni0.71Cu0.24Ga0.05O4/Sm0.2Ce0.8O2 (PNCG/SDC) layer-by-layer thin film was prepared by pulsed laser deposition (PLD) method in this study. Dense and uniform PNCG/SDC film was successfully deposited on MgO substrate. Structure of the film was analyzed with secondary ion mass spectroscopy (SIMS). Although small diffusion of cation into MgO substrate was observed, the obtained film consists of PNCG and SDC nano-sized film laminated. The electrical conductivity measurements were performed as a function of layer thickness of PNCG or SDC. The conductivity decreased with decreasing PNCG layer thickness. In contrast, the conductivity increased with decreasing SDC layer thickness. Change in electrical conductivity seems to be related with the change in lattice constant of PNCG and SDC.
