Abstract

Pulsed laser deposition (PLD) was attempted for lithium conducting electrolyte layers of Li₇La₂₃Zr₂O₁₂ on a porous membrane of anodized aluminum oxide. Al-doping made it possible to obtain dense PLD targets with the cubic garnet phase structure successfully using a solid-state reaction and sintering at 1100°C. Substrate heating during deposition led to homogeneous film morphology, but caused formation of La₂ZrO₇ impurity phase. Aluminum migration from the substrate to the film surface was observed when the sample was annealed at 700°C. The aluminum migration seemed to be facilitated by the lithium in the environment of the PLD chamber.
