The interaction of submonolayer lead deposits with oxygen pre-exposed Ni(1 0 0) has been investigated by Auger electron spectroscopy (AES) and low energy electron diffraction (LEED). By comparison with the Auger line shapes of metallic lead and ortho

The aim of the present work was to investigate the initial stages of NH3 interaction with nickel oxide layers formed on well-defined Ni(111) surfaces. The selected technique was x-ray photoelectron spectroscopy. Ammonia adsorption was performed at 10

The interaction of oxygen with lead-precovered Ni(100) has been investigated by Auger electron spectroscopy (AES). The oxygen chemisorption capacity decays linearly with lead coverage and is completely suppressed above 0.5 lead atom per nickel atom;

The adsorption of Pb on Ni(100) has been characterized by Auger electron spectroscopy, low energy electron diffraction, measurements of work function changes (Δφ) and crystal current measurements (ic). The lead layer grows by the Stranski-Krastanov

Evidence is found for a critical coverage of potassium, θc, at which the mode of coadsorption of oxygen suddenly changes. This change occurs precisely at the coverage required for the work function minimum. In the high coverage region there are line

The vapour deposition of Pb on Pt(111) has been characterized by Auger electron spectroscopy (AES), low-energy electron diffraction (LEED), measurements of work-function changes (Δφ) and crystal current measurements (ic). Lead growth occurs in two

A quantitative of the adsorption and co-adsorption of lead and tin on Al (111) surfaces has been made using Auger electron spectroscopy and low energy electron diffraction. The results are quite different from those previously obtained for the (100)

The adsorption of lead and tin on (100) and (410) substrates of copper at ambient temperature and at −75 ± 5°C was followed by Auger electron spectroscopy (AES) and low energy electron diffraction. Both simple and (on the (100) face) bimetallic l

Changes in secondary electron emission (SEE) during absorption of a metal vapour can be followed by measuring the changes in the net current icc flowing into the specimen crystal. Plots of icc as a function of deposition time t (for a fixed primary b

A critical appraisal is made of quantitative AES data obtained for some 30 metal monolayer on metal systems, and in particular for lead and tin monolayers on four substrate elements that have Auger emissions in the energy range 62–72 eV: Ni, Cu, Al
