Abstract

It is shown that a reduction of the three-level energy diagram proposed by Van de Walle (Phys. Rev. B 53, 11292, 1996) to describe the relaxation of non-equilibrium hydrogen distributions, to just the interstitial transport level and a distribution of traps, allows an essentially equivalent formulation of the hydrogen relaxation kinetics. The modified formulation offers the possibility of accounting for dispersive diffusion while preserving the essential multiple retrapping aspect of the original proposal.
