Pressure concentration isotherms of thin films of the palladium‐hydrogen system as modified by film thickness, hydrogen cycling, and stress
MW Lee, R Glosser - Journal of Applied physics, 1985 - pubs.aip.org
We describe the results of a novel adaptation of the volumetric technique to measurement of
the pressure concentration isotherms for thin films of the palladium-hydrogen system. The
isotherm shapes are comparable to bulk being steep in the alpha and beta phases and flat
in the mixed phase region. However, it is noted that the concentration onset of the beta
phase is smaller than bulk and drops markedly for thicknesses less than 670 A. Comparison
is made with quartz crystal microbalance results. We find a thickness dependence to the …
