Field emission display and methods of forming a field emission display

A method of forming a field emission device comprising:

• providing a substrate having a detonation temperature that is less than about six hundred and fifty degrees Celsius;
• forming a nano-supported catalyst on said substrate, said nano-supported catalyst containing a support matrix and active catalytic particles that are less than about five hundred nanometers;
• and
• conducting a hot filament chemical vapor deposition process to grow a plurality of nanotubes defining an area on said nano-supported catalyst, each of said plurality of nanotubes having a diameter that is less than about twenty nanometers and said area of said plurality of nanotubes providing an anode current density greater than 0.5 millampere per cm2.
