This project aims to develop interface engineered nanoscale ferroelectric thin films with functional properties suitable for integration. Bulk ferroelectrics form the core of traditional stand-alone electromechanical devices such as sensors, actuators and ultrasonic devices. Future applications need to be integrated into thin film form on semiconductor wafers, but the attachment to the wafer induces a mechanical constraint, which dramatically suppresses the electromechanical response. This project aims to solve this problem by "polarisation rotation", achieved by layered stacking of thin film ferroelectrics. Engineered control of ferroelectric polarization rotation could be the pathway to modern electromechanical devices.Read moreRead less

Legislation against the use of lead initiated a search for lead-free piezoelectric ceramics. This project aims to derive guidelines for the development and implementation of this new class of materials. This project will utilise an analysis technique that allows elucidation of the origin of the high strain in piezoelectric materials. A separate analysis of the three known strain mechanisms in materials with coexisting phases will innovatively correlate theory and macroscopic observation with processes on the atomic scale. The quantification of the contribution of each mechanism will lead to new insights into the enhancement of sustainable functional materials.Read moreRead less
