	abstract = {A film of niobium (similar to 15 A thick) deposited under ultrahigh vacuum (UHV) conditions on polycrystalline zirconium was studied by x-ray photoelectron spectroscopy (XPS) as it was taken through a series of sequential treatments. The Nb-Zr interface, associated with a Nb 3d(5/2) peak at 203.4 eV, is indicated to passivate the underlying Zr to oxygen and hydrogen plasma treatments, which in the absence of Nb would yield substantial oxidation. On heating to 500 degrees C, the pure metallic Nb 3d(5/2) component at 202.2 eV appears, and this change is accompanied by removal of the passivation effect on the substrate.},

	abstract = {The interaction of a film of Zr (similar to 38 Angstrom thick) deposited under ultrahigh vacuum (UHV) on to an approximately 12 Angstrom film of NbO on a gold substrate has been studied with X-ray photoelectron spectroscopy (XPS). Evidence is presented for an interfacial conversion from Zr and NbO to ZrO2 and Nb. The reactivity of this sample was studied through a series of sequential treatments. Although changes occur in the topmost layer, the Zr/Nb interfacial region, as identified by a shoulder at similar to 180 eV in Zr 3d and the 203.0 eV peak in Nb 3d, appears to be remarkably inert on heating at 300 degrees C under UHV, as well as on subjecting to O-2 and hydrogen plasma treatments.},

	abstract = {A NbO film (similar to 8 Angstrom thick) deposited on a gold substrate is shown by XPS to be relatively inert to a H-2/H2O treatment. However, when the same treatment is made following the deposition of iron (layer similar to 12 Angstrom thick), the NbO shows a much enhanced reactivity; it is converted to a higher oxide while the Fe converts to Fez03. Heating this sample to 300 degrees C under UHV conditions caused a more complete conversion of NbO to a NbO2-like oxide, while simultaneously the Fe2O3 is reduced to FeO. Further heating at 500 degrees C yielded a pure Nb2O5 film, while the FeO appears to reduce to the metallic form which then dissolves into the gold.},

	abstract = {A bimetallic film of iron and zirconium (thicknesses about 17 and 52 Angstrom respectively) was deposited on a gold substrate and studied by XPS after exposing to O-2 (approximately 10(3) L) at room temperature, and then heating at progressively higher temperatures up to 400 degrees C. An iron-oxide/iron/zirconium-oxide sandwich structure is present after the room-temperature exposure to O-2, and this work shows the ready transfer of O from the iron side to the zirconium side of the Fe/Zr interface. Fe migration also occurs at 220 degrees C and above, while by 300 degrees C this diffusion appears to cause a substantial restructuring of the ZrO2 layer.},
