Abstract

Epitaxial thin films of NaCl and KCl (prepared on Ge(100)) have been used for studies of adsorption of water vapor with photoemission and electron energy loss spectroscopy. Due to the large band gaps amounts of submonolayers to several monolayers are easily detected in UHV up to 10-4 mbar in the temperature range of 140 to 300 K. Perfect surfaces show a well ordered 2D-phase with a superstructure on NaCl. Defects are produced as steps due to incomplete annealing or as F-centers with electron bombardment. Water is desorbed from steps reversibly at room temperature and is dissociated irreversibly at F-centers.
