BERNAL, Rodrigo  y  AVILA, Alba. Reproducible Fabrication of Scanning Tunneling Microscope Tips. rev.ing. [online]. 2008, n.27, pp.43-48. ISSN 0121-4993.

Reproducible fabrication of Scanning Tunneling Microscope tips is carried out following an electrochemical procedure widely reported. Tips are made from 0.5 diameter tungsten wire. Controlling fabrication parameters (immersion in the electrochemical solution, current-voltage ranges, duration of the process, among others) we achieve aspect ratios of 0.68 and tip radii of 330 nm in the best case.

Palabras clave : Electrochemical processes; microscopy; nanotechnology; tungsten; tunneling.
