Abstract

We have developed a new experimental equipment for the ellipsometric study of a physisorption system on a surface of a metal single crystal; a vacuum chamber with an ultimate pressure of 10^-9 Pa, a substrate temperature between 40 K and 1000 K, and the automatic null ellipsometer. The adsorption isotherms of Xe/Ag(111) at temperatures between 60 K and 80 K were obtained in the wide pressure range between 10^-7 Pa and 10^-1 Pa. We found that this ellipsometer made it possible to observe layer growth of a van der Waals condensate from a submonolayer range to a thick layer where equilibrium pressure was nearly equal to the bulk saturation vapor pressure of the adsorbate.
