LiNbO3 was used popularly in a lot kinds of cut and modulus, because there are many different phase velocity and electromechanical coupling coefficient combinations in different cut and modulus. So in this thesis , we will focus on the LiNbO3 thin film. By the references [4-55], we will select four different kinds of buffer layer materials which is AlN、ZnO for the piezoelectric materials and Al2O3、SiO2 for the non-piezoelectric materials to get the better characteristics for the growing high-quality LiNbO3 thin films. We will use the silicon substrate for the integration of SAW with the maturing Si-based semiconductor devices.
