<p>This field electron emission device comprises a linear conductor wire having concave/convex on its surface and an electron emitter having electron conductivity formed on the concave/convex surface of the conductor wire. Preferably, the concave/convex is formed by a channeling performed to the surface of the conductor wire. Preferably, the electron emitter is composed of microscopic linear materials composed of selected one or combination of carbon nano-tube, carbon nano-wall, carbon fiber, graphite fiber, amorphous carbon fiber and diamond fiber.</p> |
