Abstract
The activation energy for the surface self-diffusion of epitaxial erbium crystals grown on a tungsten field emitter tip has been examined. It was found to be strongly dependent both on the crystallographic orientation of the tip and the direction of electric field applied. The values of the activation energy, calculated from Arrhenius-type plots, and also field emission patterns of epitaxial Er crystals are presented.
