摘要:
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. ©1995 American Institute of Physics.
