Strain engineering of proton conducting oxides


Project no.: P-LL-18-82

Project description:

The aim of this project is to understand and describe the influence of strain on proton conductors based on perovskite-derived oxides, in particular the influence of strain on proton conductivity.
Proton conducting perovskite based on acceptor-doped barium zirconate, cerate or their solid solutions will be used for the thin films formation by Physical Vapor Deposition (PVD) methods: Magnetron sputtering and Electron beam deposition.
The research project results will lead to the complex description of the influence of strain on the various properties of the proton conducting perovskite oxides. The results of the project will contribute to forming a general picture of electrical conductivity in oxides.
Results of the project will be presented at international conferences, at least four publications to the journals from ISI Master Journal List (JCR) will be submitted; the research results obtained within this project will be the experimental basis for preparation of PhD thesis, master theses and they will contribute to one Doctorate of Science. Moreover, thanks to the obtained results, it will be possible to optimize methods used for preparation of multilayered electrochemical devices based on proton conducting perovskites. In view of a scarcity of published data on the strain engineering of proton conductors, these studies are one of the most pioneering research in this field. Therefore, the long-term results will contribute to the development of clean energy sources. The short-term economic and societal impact the proposed project includes creating one postdoc position and one PhD scholarship so that it will contribute to increasing of employment rate.

Interngovernmental programme administrated by Research Council of Lithuania: Lithuania – Poland

Project results:

Results of the investigations realized within the framework of this project will be presented in various ways:
• Oral presentations/posters will be presented on a minimum 5 conferences (2 and 3 for Lithuanian and Polish researchers, respectively), e.g. SSI 2019, SSPC 2020;
• At least four joint Polish-Lithuanian publications will be submitted to the journals from ISI Master Journal List (JCR);
• At least two MSc theses will be defended;
• The research results obtained within this project will be a part of academic achievements required for one PhD and one Doctor of Science degree.
