Abstract
The authors describe an experimental ultra-high vacuum set-up which allows the performance of optical reflectivity and DC resistance measurements as well as Auger spectroscopy on thin metallic films prepared in situ. The use of surface plasmon excitation in attenuated total reflection (ATR) configuration, combined with the two other methods, is of particular interest for investigation of surface phenomena at metallic surfaces. As an illustration, the authors present and discuss results for bare metallic films and for films covered with very thin metallic layers.
