Abstract:
The valence electron states of a Zr-Fe getter having Zr2Fe as majority component (80% of the total volume) and their evolution upon oxidation at room temperature are studied with direct photoemission (h-nu = 21.2 and 40.8 eV) and inverse photoemission (isochromats in the range 12-21 eV). In the clean getter direct photoemission is mostly sensitive to Fe-derived states and inverse photoemission to Zr-derived states. Direct photoemission shows the modification of oxygen-p-derived states in the suboxide-oxide transition and the effect of Fe-oxygen interaction with a depletion of Fe d states near the Fermi level. Inverse photoemission shows a progressive localization of the Zr d states upon oxidation.
