Abstract
The basic concepts about the change of shape of metallic crystals or points heated in a strong electric field were formulated in the mid-1970s. However, the initial stage of this process, the so-called restructuring in an electric field, was known and studied much earlier [1–3]. The principal new discovery was the observation of crystalline growth in an electric field normal to the faces. In this instance, large crystalline outgrowths, “macrooutgrowths,” grew on the planar point faces at certain temperatures T and electric-field potentials F. The size of these outgrowths was comparable to that of the faces (i.e., thousands of angstroms). Their structure and faceting were the same as those of the point. Small outgrowths, “microprotrusions,” grew on the edges and corners of the macrooutgrowths or restructured point. The size of these was tens to hundreds of angstroms. Their local structure corresponded to that of the point [4–9]. These phenomena, first observed for tungsten, were demonstrated to be generalized over a number of other metals [10].
