abstract = {Mg2NiH4 thin films have been prepared by activated reactive
evaporation in a molecular beam epitaxy system equipped with
an atomic hydrogen source. The optical reflection spectra
and the resistivity of the films are measured in situ during
deposition. In situ grown Mg2NiH4 appears to be stable in
vacuum due to the fact that the dehydrogenation of the
Mg2NiH4 phase is kinetically blocked. Hydrogen desorption
only takes place when a Pd cap layer is added. The optical
band gap of the in situ deposited Mg2NiH4 hydride, 1.75 eV,
is in good agreement with that of Mg2NiH4 which has been
formed ex situ by hydrogenation of metallic Pd capped Mg2Ni
films. The microstructure of these in situ grown films is
characterized by a homogeneous layer with very small grain
sizes. This microstructure suppresses the preferred hydride
nucleation at the film/substrate interface which was found
in as-grown Mg2Ni thin films that are hydrogenated after
deposition. (c) 2006 American Institute of Physics.},
