Electron Emitters
Abstract
When two carbon-nanotube coated electrodes are placed at a small distance from each other, electron emission from carbon nanotubes allows a DC or AC electrical current to flow between these two electrodes. The voltage drop across these two electrodes depends on the electric field needed for emitting electrons necessary for carrying electric current and the distance between these two electrodes. This electrical coupler may find applications to high-voltage circuits, which operate at voltages of a much larger value than what is needed across the electrical coupler to supply the current. Because of the non-contact nature of this class of electrical coupler, two electrodes are allowed to move with respect to each other while keeping the gap spacing constant and allowing the DC or AC power to be coupled from one electrode to the other.
