Abstract
A method based on x-ray photoelectron spectroscopy and taking into acc ount elastic scattering of photoelectrons was used to determine the th ickness of ultrathin Au films evaporated on SiO2. The results derived from the O Is, Si 2p, Au 4f, and Au 4f/Si 2p signals measured as a fun ction of escape angle are in close agreement. The thicknesses of the f ilms deposited over periods of 3, 6, and 9 min are in the ratio of abo ut I : 2 : 3. Neglect of elastic scattering would lead to thicknesses overestimated by 20-30%.
