Outline of Final Research Achievements |
We conducted multi-scale dynamics studies of lattice properties in the La+Mn-doped SrTiO3, a new candidate of n-type thermoelectric materials, using neutron scattering. We found a clear correlation between the inelastic neutron scattering spectra and the thermal conductivities of the samples. We further performed similar studies on related materials. In parallel, we developed data analysis methods required in the neutron scattering studies and established the evaluation method of the instrumental resolutions.
