The atomic structure and chemistry of Fe-rich steps on antiphase boundaries in Ti-doped Bi0.9Nd0.15FeO3
in APL Materials
| Description | The main findings of the project relate to the effect of strain around local precipitates and defects on the polar order in BiFeO3 based ceramics. Nano-rods and APBs formed by doping with TiO2 create a local environment which modifies the domain structure and can lead to the stabilisation of polar rather than antipolar order |
| Exploitation Route | The findings have been published major international journals with high impact factor and have bee presented as part of plenary and invited talks at major international conferences |
| Sectors | Aerospace, Defence and Marine,Electronics |
| Description | The findings have been used as part of a greater understanding of the role of dopants in BiFeO3 and in the complex crystal chemistry which controls its properties. The data has led to greater control of the phase assemblage and overall superior ceramics |

| Results and Impact | The research formed the basis of multiple invited presentations at international conferences, e.g. Electronic Materials and their Applications, Electroceramics, International Symposium on Applied Ferroelectrics. The audience members varied from post graduate researchers to faculty in other universities (professional practioners). The research was also presented at Glasgow University and Liverpool University in their seminar series. |
