The Crystalline Structures of Sputtered and Evaporated Metallic Films.

Abstract

Crystalline structures of evaporated films of bismuth and silver, condensed on a cool surface, were determined by the X-ray powder method. The films were found to contain no pure metal in the crystalline state, but to consist of amorphous metal and of metallic compounds. Optical evidence indicates that selenium also condenses on a cool surface in the amorphous form, although on a heated surface crystals are deposited whose size and color depend on the temperature.
