Keywords:scanning tunneling microscopy, electrochemical etching

PtIr has widely used for a tip of scanning tunneling microscopy, and AC electrochemical etching method has been widely used for the preparation. However, the mechanism of the AC electrochemical etching was out of interest. In this paper, we have investigated the frequency dependence of the AC electrochemical etching of the PtIr wire.
