Advanced materials for a high temperature unicouple (THERMAT)


The objective of the project is to contribute to the development of the efficiency - harmonized thermoelectric unicouple with a high thermoelectric performance and chemical stability at elevated temperatures, i.e. to perform a complex material research of multiply doped ZnO (n-type leg) and low-valence molybdenum selenides (p-type leg). The advanced technologies of thermally assisted material compaction such as hot pressing (HP) and spark plasma sintering (SPS) will be used to sinter the final specimens. As the standard characterization tools are available in both laboratories the evaluated thermoelectric characteristics will serve as an indispensable feedback for the improvement of sample properties. Simultaneously we aim that the mutual confrontation of measured thermoelectric data will significantly improve the credibility of evaluated thermoelectric parameters.
