Nanostructure field emission cathode structure and method for making

摘要

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.
