Abstract: Most high-temperature ferroelectric materials have relatively low piezoelectric coefficients, which limits their sensor applications. In this study, we propose vanadium (V) doping to improve the ultrasonic performance of LiNbO 3 film transducers deposited by RF magnetron sputtering. In order to achieve doping within a wider range of V concentrations, a small V inlaid target asymmetrically embedded in the main lithium niobate target was used. The V concentration in the deposited films is a decreasing function of the radial distance from the V target, corresponding to the change in film composition from LiNb 0.866 V 0.134 O 3 to LiNb 0.977 V 0.023 O 3. The maximum measured d 33 constant of LiNb 0.935 V 0.065 O 3 film is about three times that of undoped LiNbO 3 film, which are 14 pC/N and 4.8 pC/N, respectively. A comparative study was conducted on the surface morphology, microstructure, phase and element composition, piezoelectric and ferroelectric properties, ultrasonic wave generation efficiency, high-temperature ultrasonic performance, and high-temperature durability of undoped and V-doped LiNbO 3 films with different V concentrations. In order to study high-temperature durability, a protective high entropy alloy oxide layer was added to the transducer structure. The V doping of LiNbO 3 films proposed in this study demonstrates high efficiency, making the doped LiNbO 3 material comparable to widely used but not high-temperature ZnO piezoelectric material.
