Abstract
Example embodiments presented herein are directed towards an electron emitter for an x-ray tube. The electron emitter comprises an electrically conductive substrate and a nanostructure material. The nanostructure material is comprised on at least a portion of the electrically conductive substrate. The nanostructure material is made of oxides, nitrides, silicides, selenides or tellurides. Such an electron emitter may be used for hybrid emission, such as Schottky emission or field emission.
