Single-Crystal Growth of Gold on the Tungsten Autocathode
Abstract
The conditions of Au crystal production on W field emitter have been studied by the field emission microscope. The results have shown that 'microfield emitter' increases field emission and its stability. The significance of transition layers on a metal substrate for crystallization is discussed. Wide use of method of autoelectronic microscopy both in research and in practical region requires together with use of high-melting materials, decontaminated with heat treatment, expansion of wheel/circle of substances, suitable for use as autocathodes. Under-ice to a considerable degree it was possible to achieve the complete auto-emission current from 'whiskers', grown from the vapors under high-vacuum conditions. By this method together with the desorption by field are obtained the auto-emitter, which give the symmetrical picture of surface, and for the materials with the low melting point, in particular gold. Obtaining field emission current from the projections of low-melting substances to the surface of point is proposed. Russian translation.
