Abstract
ALTHOUGH considerable effort in electron spectroscopy for chemical analysis (ESCA) has been channelled into the development of narrow line sources1–4, there has been little attention to the problem of increasing ESCA resolution by decreasing the large linewidth contribution from involatile non-conducting solid samples. For such samples, most workers have spread a thin layer of solid on to sticky tape5,6, or have used a metal mesh as host matrix7–9. Al has also been suggested as a sample backing by P. E. Larsen. These procedures generally provide widths approximately 1 eV broader than those from the gas phase1, thin condensed phase10, or from conductor1 spectra. The procedures normally involve the use of a few mg of compound, even though ESCA should be sensitive to ∼ 10−8 g of a material2,11.
