Nanotips with desirable apex atomic structures

Technology Overview

The developed method of fabricating a super nano ion-electron source can lead to improved nanotips for applications in nanotechnology, particularly in scanning probe microscopy and electron microscopy. The method involves placing an assembly of precursor tip with an apex and a shank and a heating metal ring in a field ion microscope chamber, applying a direct current to heat the metal ring, applying an electrical field to the precursor tip, and monitoring the evolution of the tip apex until sharpened to a desirable structure.
