The Use of the Field Emission Electron Microscope in Adsorption Studies of W on W and Ba on W

Abstract

The chief conclusions from these studies are given in the Introduction. Table II summarizes the adsorption properties of W on W and Ba on W. These properties vary with the crystal plane and are given for five planes. The extent to which these planes develop depends on T and the applied field, F. The temperature at which W atoms migrate on W at detectable rates depends on the plane and on F, and varies from 800 to 1200°K.
