Abstract

The surface composition of PbO has been studied with X-ray photoelectron spectroscopy after bombardment with several inert gas ions of 400 eV. The results show reduction of PbO to metallic Pb with the degree of damage following the order He+ > Ne+ >Ar+. Both Kr+ and Xe+ did not reduce the oxide. The depth of damage varied from ≈9 Å for He+ to ≈1 Å for Ar+ bombardment. The results were compared to a collisional and a thermal model of the sputtering process.
