The interaction between Fe and NiO(001) surface for increasing metal deposition at RT was studied by means of Xray photoelectron spectroscopy and X-ray photoelectron diffraction. NiO reduces to an extent that depends on the amount of deposited Fe, up to a maximum of 1 ML for Fe deposition of 5 ML or larger. The overlayer initially grows in a 3D island mode, with partial intermixing between the deposited Fe atoms and the metallic Ni atoms resulting from the reduction process. The intermixed region extends up to about 3 M L. For 5 ML Fe deposition, the islands coalesce into a continuous film.

Abstract
The interaction between Fe and NiO(001) surface for increasing metal deposition at RT was studied by means of Xray photoelectron spectroscopy and X-ray photoelectron diffraction. NiO reduces to an extent that depends on the amount of deposited Fe, up to a maximum of 1 ML for Fe deposition of 5 ML or larger. The overlayer initially grows in a 3D island mode, with partial intermixing between the deposited Fe atoms and the metallic Ni atoms resulting from the reduction process. The intermixed region extends up to about 3 M L. For 5 ML Fe deposition, the islands coalesce into a continuous film.File in questo prodotto:
