  4. 8. Dynamical properties of metal halide and oxyhydride perovskites

    Författare :Rasmus Lavén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; perovskite; quasielastic neutron scattering; phonon; inelastic neutron scattering; diffusion; oxyhydride; hydrogen dynamics; Metal halide perovskite; hydride ion.;

    Sammanfattning : This thesis concerns investigations on the dynamical properties of two classes of energy-relevant materials, namely metal halide and oxyhydride perovskites, using neutron scattering techniques. These two classes of materials share the same aspect of a perovskite-type crystal structure but are different in terms of their functional properties and concomitant promise for various technological applications.
