Expected results

             The overall scientific goal is to improve the knowledge concerning the role of porosity on the nonlinear dielectric properties and switching responses in a few classes of oxide perovskites in their ferroelectric/paraelectric state by a multidisciplinary approach. The project involves advanced original modeling tools, innovative chemistry for the sample preparation, nano/microscale characterization and detailed investigation of the functional properties. The grant will produce long-term innovation and knowledge by clarifying the complex contribution of porosity on the polarization mechanism in multifunctional materials for their use in new types of devices.

 The deliverables of the project are:

1. A model capable to describe the role of porosity level and phase interconectivity on tunability properties

2. A model capable to describe switching properties in porous ferroelectrics at various length scales

3. Perovskite powders in paraelectric and ferroelectric state

4. Porous para/ferroelectric materials with different microstructures (interconnectivity between pores and bulk component)

5. At least one porous ceramic proposed for tunability applications

6. Final report and publications concerning the role of porosity and microstructural characteristics on the functional properties of porous ferroelectrics

 

Dissemination of the results:

            The expected potential long-term knowledge and innovation will be promoted by an efficient dissemination strategy:

1. Valuable publications (at least three papers with a total impact factor higher than 6);

2. Participations to at least three international conferences;

3. Project website;

4. Results to be exploited in one PhD thesis and one master degree thesis.

 The expected scientific impact is related to:

1. Contributions to basic science related to understand the role of porosity on tunability and switching properties of ferroelectrics;

2. A large impact is expected on the ferroelectrics community, by elucidation of polarization mechanism in porous ferroelectrics, by using the original modeling approach;

3. Connect the young Romanian group to a highly innovative field of research and ensuring active collaborations with EU partners in the common field of interest;

4. Increase the visibility of Romanian science at international level by resulting in high-impact publications.
