Influence of oxygen defects and atomic displacement parameters in thermoelectric Ca0.9Yb0.1MnO3-d prepared by alternative synthesis methods
Trough this experiment we'll analyse the role played by the oxygen stoichiometry, the ordering of the oxygen sublattice and the crystal structure on the thermoelectric properties of Ca0.9Yb0.1MnO3-d obtained by different synthesis methods: conventional solid-state reaction, hydrothermal, sol-gel, combustion and assisted microwave synthesis. Preliminary characterization (transport and laboratory XRD measurements) points to a strong influence of oxygen (content and ordering sublattice) on the properties of each sample and this is strongly related with the synthesis procedure. Additionally, a detailed inspection of the atomic displacement parameters (ADPs) will be related with the magnitude of the lattice thermal conductivity for each case.
