Hydrogen Diffusion in Nanostructured HfTi2: A Green’s Function Approach

Antony Muthian, Lawrence Nalathambi and John Bosco Balaguru Rayappan    

Abstract: The Laves phases binary intermetallic compound HfTi2 is one of the potential candidates for the storage of hydrogen. The knowledge on thermal properties of hydrogenated HfTi2 is important in order to use this material for hydrogen storage application. This study has reported important thermal properties such as phonon frequency distribution, defect modes, mean square displacement and diffusion parameters of H in the hydrogenated HfTi2 using lattice dynamical investigation involving green’s function method and scattering of phonons by defect space atoms.
