<p>Provided are a hybrid composite including a carbon nanotube and a carbide-derived carbon, an electron emitter including the hybrid composite, and a method of preparing the electron emitter, and an electron emission device including the electron emitter. Specifically, provided are a hybrid composite including a carbon nanotube and a carbide-derived carbon prepared by thermochemically reacting a carbide compound with a halogen group element-containing gas so that all of the elements except for carbon, constituting the carbide compound, are extracted, an electron emitter including the hybrid composite, and a method of preparing the electron emitter, and an electron emission device including the electron emitter. Since the carbon nanotube and the carbide-derived carbon are hybridized and composited, a screen effect that may occur when a great amount of carbon nanotubes are used can be prevented, and an electron emitter including the hybrid composite has excellent electron emission capability, excellent uniformity, and long lifetime.</p> |
