| Outline of Final Research Achievements |
Neutron total scattering measurements of Li7P3S11 metastable crystal and (Li2S)70(P2S5)30 glass were performed at room temperature. Atomic PDF (Pair Distribution Function) analysis showed different crystallite size for metastable crystal and (Li2S)70(P2S5)30 glass. Bold Valence Energy Landscape obtained from the structural information is available for investigating chemical bonding characteristics and atomic diffusion potential.
