Domain wall contributions to piezoelectricity in relaxor-lead titanate single crystals
in Acta Materialia
| Description | Piezoelectric coefficient in PMN-PT is dependent upon domain wall density and is augmented by domain wall broadening rather than domain wall translation. An alternative lead free piezoelectric material system was identified known as KBMN-KBT; optimisation is still on-going. |
| Exploitation Route | The findings will help develop new materials. |
| Sectors | Electronics Energy |
| Description | Findings from this project have contributed to new work in collaboration with spin-out company Ionix Advanced Technologies Ltd to identify new lead-free piezoelectric materials funded by Innovate UK. |

| Results and Impact | My work and publications from recently funded EPSRC projects led to me being appointed as Distinguished Lecturer in Ferroelectrics for the IEEE Ultrasonics, Ferroelectrics and frequency Control Society. This provided mw with a budget of $20,000 to undertake outreach lectures around the world during 2023. I completed 27 lectures in China, Japan, USA, Canada, UK, Finland, Germany, Croatia and Slovenia, mainly at university and industry locations. |
