摘要：

Lanthanum lithium titanate thin films were grown by Pulsed Laser Deposition. La0.57Li0.29TiO3 dense films with smooth surfaces were obtained after optimization of the growth parameters. Such films deposited at 700 degrees C under 15 Pa are nano-crystalline with domains corresponding to the cubic and tetragonal modifications of this phase. In relation to the measured conductivities/activation energy and to previous works, we clearly underlined that the films of practical interest, prepared at relatively low temperature, are predominantly formed from the tetragonal ordered phase.
