Abstract
A device for controlling electron flow is provided. The device comprises a cathode, an elongate electrical conductor embedded in a diamond substrate, an anode, and a control electrode provided on the substrate surface for modifying the electric field in the region of the end of the conductor. A method of manufacturing the device is also provided.
Claims12
A device for controlling electron flow, the device comprising:
- a cathode;
- at least one elongate electrical conductor embedded in a substrate comprising diamond, wherein the or each said conductor is in electrical communication with the cathode;
- an anode, wherein the or each said conductor is adapted to emit electrons from an end thereof remote from the cathode through the substrate to the anode;
- at least one control electrode for modifying the electric field in the region of the end of the or each said conductor;
- and
- at least one layer of insulating material wherein the or each said control electrode is separated from the or each said conductor by said insulating material, and wherein at least one said control electrode has at least one first aperture arranged such that electrons emitted from the end of the or each said conductor remote from the cathode pass through a said first aperture to said anode.
