Effects of bias voltage on the structure and ultrasonic response of LiNbO3 film transducers deposited by magnetron sputtering
In this study, we deposited LiNbO3 film ultrasonic transducers using RF magnetron sputtering technique. The effects of bias voltage applied to the samples, heat treatment, and deposition geometry on the structure, morphology, element distribution, phase composition, and piezoelectric properties of transducers were studied. The bias voltage significantly improves the uniformity of element distribution and partially suppresses the formation of secondary phases (LiNb3O8, NbO, and Nb2O5). The optimal bias value was within the range of 4–25 V, and higher bias voltages resulted in degradation of the transducer structure and piezoelectric performance. Short term heat treatment in air at 700 °C for 5 h significantly improved ultrasonic response. The influence of transducer thickness and tilt angle of columnar structure on piezoelectric response was also discussed. The maximum longitudinal and shear wave amplitudes were observed at tilt angles of 0 and ∼15 deg, respectively.
期刊介绍：
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
