Electron paramagnetic resonance as a probe for extended interfaces in nanomaterials

Electron paramagnetic resonance as a probe for extended interfaces in nanomaterials

Objective

Ferroelectric materials are considered for applications in telecom devices opera ting at high frequency such as phase shifters, antennas or resonators. With the increasing requirements for miniaturization and low cost electronics, the market is nowadays widely turned to agile components and there is in particular a strong competition for the search of new materials. The best candidates for such applications are ferroelectric (FE) materials. Their distinctive advantage among all other materials is that their dielectric permittivity may be tuned under the application of moderate electric field. Of particular interest for this project are nanosize materials based on the barium titanate: composites, thin films and multilayers. In all these materials charge defects are playing very important role and EPR as the most sensitive method for paramagnetic defects and their local environment will be used to detect such defects and their position in: i) core or shell; ii) film or substrate; iii) interfaces; iv) surfaces. The main aim of this project is to use long time close cooperation of physicists and materials scientists to develop new methodology in materials design based on EPR application for the new materials creation with properties of demand.
