Abstract

Pulsed laser deposition was used to grow epitaxial LiNbO3 films on sapphire(0001) substrates with a single crystal LiNbO3 target. Using deposition temperatures below 450 °C, LiNbO3 films with correct stoichiometry could be grown without using Li-rich targets. Rutherford backscattering spectrometry measurements showed that the oxygen to niobium ratio is 3.00 ± 0.15 to 1.00. It was also found that the crystallographic orientations of the LiNbO3 films could be controlled by adjusting the oxygen pressure during deposition. An x-ray pole figure shows that epitaxial LiNbO3 films were grown on sapphire(0001), but with twin boundaries.
