An experimental study of the interaction of hydrogen with the Mg(0001) surface
The interaction of atomic and molecular hydrogen with the (0001) surface of magnesium has been studied using EELS, TDS, work-function measurements, and core-level spectroscopy. No evidence for molecular or dissociative adsorption of H2 is observed at the substrate temperature investigated (>110 K, atomic hydrogen is bound to the surface in a strongly chemisorbed state (surface hydride), which is a metastable phase. When the substrate is annealed to 425 K, no desorption occurs but the system converts irreversibly to a chemisorbed phase wherein the hydride characteristics are absent. The results are compared to existing theoretical studies. © 1991.
