Abstract
Characteristic vapor‐grown tungsten whiskers on tungsten substrates were studied by means of a field emission and a transmission electron microscope. The whisker growth was found to be induced by high‐field vacuum discharges caused by tungsten oxide vapors. By transmission electron microscopy of a typical specimen, evidence was obtained that the whisker growth can be accounted for by the screw‐dislocation mechanism of crystal growth.Keywords
