Layers of carbon, oxygen, sulfur and potassium adsorbed on an Fe(100) surface were studied by LEED, AES and XPS. When examined quantitatively by XPS, saturated c(2 × 2)CO(β), c(2 × 2)C and p(1 × 1)O surface structures yielded the C/O ratios expected from surface coverages of 0.25, 0.5 and 1.0 monolayer, respectively. When these results were normalized to the equivalent coverages of 1.0 monolayer, the relative XPS cross-sections obtained for S, O, C and K were found to agree closely with the results of theoretical calculations. The results illustrate the use of these techniques for the quantitative determination of surface coverages.
