Photoemission studies of the W(110)/Ag interface

Electron spectroscopy studies of surface In–Ag alloy formation on the tungsten surface

“…Fig. 1a presents spectrum obtained for the The spectrum reveals two most prominent lines observed at 4.55 AE 0.05 eV and 4.93 AE 0.05 eV, corresponding to photoemission from the Ag4d valence orbitals and agrees well with the results obtained earlier for the Ag/W(1 1 0) system [10,[15][16][17].…”

“…Silver coverages were determined from XPS intensities of the Ag3d and W4d corelevel transitions. The absolute calibration was performed by combining LEED and UPS results, as well as the Ag-induced change in work function DF [10]. All depositions were performed with the substrate at room temperature.…”

“…In particular with noble metal overlayers no alloying occurs and the sample can be cleaned after each deposition step by thermal desorption of the adsorbate [10]. No dissolution and alloying of indium in tungsten and formation of intermetallic compounds were also found for the In-W system [11].…”

Study of Ultrathin In-Ag Layers οn Tungsten by Means of Surface Spectroscopy Techniques

“…Silver coverages were determined by using the XPS intensities of the Ag 3d and W 4d core levels. The absolute calibration was performed by combination of LEED and UPS results as well as on the Ag--induced change in work function ∆Φ [13]. All depositions were performed at room temperature of the substrate.…”

“…In particular with noble metal overlayers no alloying occurs and the sample can be cleaned after each deposition step just by thermal desorption of the adsorbate [13]. No dissolution and alloying of indium in tungsten and formation of intermetallic compounds were also found for the In-W system [14].…”
