摘要：

A simple, two-stage procedure is shown to produce slender and ultrasharp tungsten tips of nanometer and subnanometer apex dimensions (nanotips). Tip sharpening is achieved by electrochemical etching through bubble dynamics induced by ac voltage in a novel configuration in which the wire end is oriented upward. Tip shape is characterized by high-resolution transmission electron microscopy.
