Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description The most important finding has been in finally elucidating the actual local structure of the important piezoelectric material PZT after some 40 years of work. The paper published in Nature Comms. received the Spriggs Award from the American ceramics Society as the most important ceramics contribution in that year. The importance of this work is that we now understand better how to design new piezoelectric materials.
Exploitation Route The basic analysis points a way to create new lead free piezoelectrics.
