Processing and electrical conductivity of lanthanum gallate core-shell heterostructures

Processing and electrical conductivity of lanthanum gallate core-shell heterostructures

The electrical properties of a lanthanum gallate solid electrolyte were modified by selectively doping the grain boundaries with Fe. This was achieved by sandwiching a La0.95Sr0.05Ga0.90Mg0.10O3-δ (LSGM) dense pellet between LaFeO3 samples. Annealing at 1550°C in air for several hours promoted Fe di...
