A. Abromeit et al., THICKNESS DEPENDENCE OF THE HYDROGEN SOLUBILITY IN EPITAXIAL NB(110) FILMS GROWN ON AL2O3(11.0) SUBSTRATES, Journal of alloys and compounds, 253, 1997, pp. 58-61
Hydrogen solubility isotherms of thin epitaxial Nb(110) films were mea
sured via in-situ X-ray Bragg scattering. The lattice parameters were
converted to H-concentrations through additional neutron reflectivity
measurements on the same samples at specific points on the isotherms.
The isotherms depend strongly on the film thickness, as regards the sl
ope in the plateau region and the saturation concentration.
