Soft Anharmonic Coupled Vibrations of Li and SiO4 Enable Li-ion Diffusion in Amorphous Li2Si2O5
Sajan Kumar, Mayanak K. Gupta, Prabhatasree Goel +7
We present the investigations on atomic dynamics and Li+ diffusion in crystalline and amorphous Li2Si2O5 using quasielastic (QENS) and inelastic neutron scattering (INS) studies su…

Solid-like to Liquid-like Behavior of Cu Diffusion in Superionic Cu2X (X=S, Se): An Inelastic Neutron Scattering and Ab-Initio Molecular Dynamics Investigation
Sajan Kumar, M. K. Gupta, Prabhatasree Goel +5
Cu2Se and Cu2S are excellent model systems of superionic conductors with large diffusion coefficients that have been reported to exhibit different solid-liquid-like Cu-ion diffusio…
