Epitaxial thin films of the Li-ion conducting solid electrolyte Li0.33La0.56TiO3 were grown by pulsed laser deposition. The growth temperature and oxygen partial pressure required for crystallization were higher than 900 degrees C and 5 Pa. respectively. Further optimization of growth conditions led to the formation and orientation control of Li-ion conducting epitaxial Li0.33La0.56TiO3 thin films. (C) 2012 Elsevier B.V. All rights reserved.
