Synthesis and orientation control of Li-ion conducting epitaxial Li_(0.33)La_(0.56)TiO_3 solid electrolyte thin films by pulsed laser deposition

摘要

Epitaxial thin films of the Li-ion conducting solid electrolyte Li_(0.33)La_(0.56)TiO_3 were grown by pulsed laser deposition. The growth temperature and oxygen partial pressure required for crystallization were higher than 900 °C and 5 Pa, respectively. Further optimization of growth conditions led to the formation and orientation control of Li-ion conducting epitaxial Li_(0.33)La_(0.56)TiO_3 thin films.
