Abstract
Fabrication of an electron-emitting device entails distributing electron-emissive carbon-containing particles (22) over a non-insulating region (12). The particles can be made electron emissive after the particle distributing step. Particle bonding material (24) is typically provided to bond the particles to the non-insulating region. The particle bonding material can include carbide formed by heating or/and can be created by modifying a layer (32) provided between the non-insulating region and the particles. In one embodiment, the particles emit electrons primarily from graphite or/and amorphous carbon regions. In another embodiment, the particles are made electron-emissive prior to the particle distributing step.
