Abstract
Tapered silicon structures, of interest for use, e.g., in atomic force microscopes, in field-emission devices, and in solid state devices are made using silicon processing technology. Resulting tapered structures have, at their tip, a radius of curvature of 10 nanometers or less. Such preferred silicon structures are particularly suited as electron emitters in display devices.
