Inelastic neutron scattering study of the lattice dynamics of the green semiconducting calcium silicides for thermoelectric applications
We wish to study the lattice dynamics, phonon anharmonicity, and structural characteristics of Ca3Si4 and Ca14Si19 by inelastic neutron scattering and neutron diffraction. Ca3Si4 and Ca14Si19 are semiconducting Zintl compounds showing electronic and transport properties marking them excellent materials for thermoelectric applications. One key feature contributing to their excellent thermoelectric behavior is their very low lattice thermal conductivity. To date, their depleted thermal transport has not been understood and only a few attempts have been undertaken to shed light on the microscopic mechanism of the low thermal conductivity. Here we ask for temperature-dependent inelastic and diffraction experiments to study the vibrational properties responsible for thermal transport in the compounds in every detail.
