Abstract
A bimetallic film of iron and zirconium (thicknesses about 17 and 52 A ngstrom 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 degr ees C. An iron-oxide/iron/zirconium-oxide sandwich structure is presen t 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, wh ile by 300 degrees C this diffusion appears to cause a substantial res tructuring of the ZrO2 layer.
