ELECTRON MICROSCOPE STUDIES OF EVAPORATED CADMIUM AND ZINC

Abstract

Employing a technique, previously described, whereby evaporations are carried out within the specimen chamber of an electron microscope, continuous observations have been made on the formation of evaporated deposits of cadmium and zinc. The particles first seen appear suddenly, have a regular crystalline shape, and are often relatively large (200 Å). At first they remain regular while increasing in size, but later develop irregular spurs, secondary crystallites, or link together with their neighbors. This behavior is quite different from that of silver and gold in which the aggregates appear irregular at all stages.
