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 deformation 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 twenty nanometers;
• and
• conducting a thermal chemical vapor deposition process to grow nanotubes having a density between 104 and 5×109 per cm2 on said nano-supported catalyst, each of said nanotubes having a diameter that is less than about twenty nanometers, a height of less than about 10 micrometers.

A method of forming a field emission device comprising:

• providing a substrate having a deformation 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 nanotube on said nano-supported catalyst, said nanotube having a diameter that is less than about twenty nanometers.
