Abstract
Various embodiments are described herein for nanostructure field emission cathode structures and methods of making these structures. These structures generally comprise an electrode field emitter comprising a resistive layer having a first surface, a connection pad having a first surface disposed adjacent to the first surface of the resistive layer, and a nanostructure element for emitting electrons in use, the nanostructure element being disposed adjacent to a second surface of the connection pad that is opposite the first surface of the connection pad. Some embodiments also include a coaxial gate electrode that is disposed about the nanostructure element.
