A field emission device and method of forming a field emission device are provided in accordance with the present invention. The field emission device is comprised of a substrate ( 12 ) having a deformation temperature that is less than about six hundred and fifty degrees Celsius and a nano-supported catalyst ( 22 ) formed on the substrate ( 12 ) that has active catalytic particles that are less than about five hundred nanometers. The field emission device is also comprised of a nanotube ( 24 ) that is catalytically formed in situ on the nano-supported catalyst ( 22 ), which has a diameter that is less than about twenty nanometers. |
