Abstract

Highly textured La0.8Sr0.2Ga0.8Mg0.2O3 (LSGM) films with columnar structure were grown by pulsed laser deposition on (001) NdGaO3 and SrTiO3 buffered (001) MgO substrates. Combined analysis of the films structure and morphology and EIS measurements showed that the transport properties are mainly limited by perpendicular grain boundaries effects. Increasing the film thickness, columnar nanosized grains tend to coalesce leading to a decrease of grain boundary concentration, hence to enhanced conductivity.
