Abstract

Chlorine adsorbed on either air-cleaved or water-treated NaCl surfaces prior to metal deposition proved to be active as a surfactant promoting the epitaxial growth of silver, gold and copper at low temperatures (80-120 °C), while no epitaxial orientation of aluminium layers was found under these conditions. Treatment of surfaces of Kyropoulos-grown NaCl with bidistilled water resulted in no significant improvement in the orientation of vacuum-deposited silver, gold and copper, but after exposing the water-treated surfaces to chlorine gas prior to evacuation, epitaxial orientation of the vacuum-deposited metals was found. Changes in the nucleation density of the metals and in the cleavage step structure on NaCl due to different treatments were studied by surface decoration. A correlation between the presence of active chlorine on the NaCl surface and the epitaxial temperature of deposits has been proposed.
