ABSTRACT
The unconventional properties of nanoscale materials have received much attention due to their potential uses in both mesoscopic research and the development of nanodevices. It is well known that nanostructures with sharp tips are promising materials for applications as cold cathode field emission devices. Various materials containing carbon have evoked great interest as cold cathode materials for field electron emission for flat panel displays.1-3 It is found that field emission can occur at a much lower turn-on field with carbon materials as compared to other materials. The carbon-containing materials include carbon nanotubes, amorphous carbon, diamonds and diamond-like films, and silicon carbide layers.
