Undergraduate Thesis. June 2008. Electronics Engineering Department, Pontificia Universidad Javeriana. Bogotá, Colombia.

We designed, constructed and test a system for the fabrication of sharp metal tips with nanoscale diameter. The fabrication of the tips is based on an electrochemical reaction between an anode and a cathode immersed in a chemical solution. The system allows to control temperature, voltage, current and chemical concentration. The process in visualized in real time and data is stored. The system was part of the project “Construction of a system of probe exploration by tunneling effect for nanoscalar measurement” of the research group of Nanoscience of the Pontificia Universidad Javeriana.
