Colombi, G. (author), De Krom, Tom (author), Chaykina, D. (author), Cornelius, S. (author), Eijt, S.W.H. (author), Dam, B. (author)Rare-earth oxyhydride REOxH3-2x thin films prepared by air-oxidation of reactively sputtered REH2 dihydrides show a color-neutral, reversible photochromic effect at ambient conditions. The present work shows that the O/H anion ratio, as well as the choice of the cation, allow to largely tune the extent of the optical change and its speed. The...journal article 2021

Singh, S. (author), Eijt, S.W.H. (author)We report ab initio calculations based on density-functional theory, of the vacancy-mediated hydrogen migration energy in bulk NaH and near the NaH(001) surface. The estimated rate of the vacancy mediated hydrogen transport, obtained within a hopping diffusion model, is consistent with the reaction rates of H-D exchange in nano-NaH at the...journal article 2008
