Abstract

We report a modified procedure to fabricate electrochemically etched scanning tunneling microscopy tips under ac voltage. By both confining the etching action to a small region and controlling the etching current on a tungsten wire, we produce ultrasharp tips with low-aspect ratio. No electronic shut-off control is required. Atomic resolution images are routinely obtained.
