Abstract
Particles, which may include nanoparticles, are mixed with carbon nanotubes and deposited on a substrate to form a cold cathode. The particles enhance the field emission characteristics of the carbon nanotubes. An additional activation step may be performed on the deposited carbon nanotube mixture to further enhance the emission of electrons.
