Abstract

Abstract The diffusivities and activation energies of atomic and molecular hydrogen in amorphous ZrO 2 (a-ZrO 2 ) of different densities were calculated using molecular dynamics methods. Atomic hydrogen was found to be diffusing via forming and dissociating bonds with oxygen atoms in a-ZrO 2 . The energy barriers for three H transport means were calculated and the most significant component of short term H transport was identified.
