THE INFLUENCE OF SUBSTRATE TEMPERATURE ON THE STICKING COEFFICIENT OF ZINC ON GLASS

Abstract

The influence of glass substrate temperature between room temperature and 95C on the sticking coefficient of zinc-on-glass in a vacuum of 0.000001 torr was studied. The sticking coefficient was found to be significantly higher at 65 to 95C. At room temperature no adsorption of zinc was observed even after the glass surface was exposed to a high flux of zinc vapor atoms for 15 minutes. Contamination effects on the sticking coefficient are described; it was noted that at temperatures within the range of 65 to 95C a uniform and continuous film of zinc deposited on glass slides cleaned with nitric acid and water. The effect of change in the flux of the zinc vapor on the sticking coefficient is also discussed. Three theories are proposed to explain the phenomena of increased sticking of zinc with increased substrate temperature.
