A substrate for a field emitter suitable for use in computed tomography has a coating with carbon hybrid structures based on the allotropes graphite, graphene and nanotubes. The field emitters are based on graphite layer structures. A substrate for field emitters is achieved for the first time that uses “graphite combs” protruding and aligned essentially perpendicular to the substrate as well as hybrid materials from these combs with CNTs supported between them on a conductive substrate.
