Abstract :
0.95(K0.48Na0.52NbO3)-0.05(LiSbO3) (95KNN-5LS) thin films have been fabricated by pulsed laser deposition (PLD) on Pt/Ti/SiO2/Si substrates. The K-rich in the target and the fabrication parameters on the properties of the films was investigated. The results show that good films can be obtained with the 0.95(K0.48Na0.52NbO3)-0.05(LiSbO3)-0.0228K2CO3 (95KNN-5LS-4.56K) target, and the surface roughness, film orientation, composition and properties of the films are strongly dependent on the oxygen pressure and oblique angle from the plume axial direction in PLD process.
