The postdoctoral student Julian Walker gave a talk on an international conference in Russia on the project’s results related to the BiFeO3-SmFeO3 ceramic system. The presentation was focused on the comparison of the functional response and domain structure of unmodified and Sm-modified BiFeO3. During the conference, Julian received the “Excellence award for the best oral presentation of young scientist”.
E.02 International awards
COBISS.SI-ID: 27854375The invited talk was given at ISAF (International Symposium on Applications of Ferroelectrics), a leading conference in the field of ferroelectrics, which was held in State College, USA. The project leader presented the last project’s results on the piezoelectric behavior of BiFeO3 ceramics. In particular, he showed the nonlinear piezoelectric response of BiFeO3 at low driving field frequencies, which is distinctly different from that of the morphotropic Pb(Zr,Ti)O3 (PZT). The mechanism that links the dynamics of the conductive domain walls in BiFeO3 with the macroscopic piezoelectric response was explained in detail.
B.04 Guest lecture
COBISS.SI-ID: 27726375Within the project we collaborate with prof. Dragan Damjanovic from Swiss Federal Institute of Techology, Switzerland. Prof. Damjanovic gave an invited talk on the traditional MRS (Materials Research Society) conference in Boston, USA. He presented the project results related to the nonlinear Maxwell-Wagner piezoelectric response of BiFeO3, which has origin in the motion of conductive domain walls under subswitching electric and stress fields.
