Abstract

A convenient treatment that can be applied to tungsten scanning tunneling microscope tips prepared by electrochemical etching in aqueous base is described. The treatment removes the majority of the tungsten oxide layer present after etching and produces a very stable tunnel junction and a high success rate in preparing tips for atomic‐resolution imaging.
