Patent number: 6902458Abstract: An emitter has an electron supply layer and a silicon-based dielectric layer formed on the electron supply layer. The silicon-based dielectric layer is preferably less than about 500 Angstroms. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within which the silicon-based dielectric layer is formed. A cathode layer is formed on the silicon-based dielectric layer to provide a surface for energy emissions of electrons and/or photons. Preferably, the emitter is subjected to an annealing process thereby increasing the supply of electrons tunneled from the electron supply layer to the cathode layer.Type: GrantFiled: January 12, 2004Date of Patent: June 7, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Zhizhang Chen, Michael David Bic, Ronald L.

Patent number: 6741016Abstract: An electron lens is used for focusing electrons from a cathode to an anode. The lens includes a first conductive layer with a first opening at a first distance from the cathode. The first conductive layer is held at a first voltage. The lens also includes a second conductive layer with a second opening at a second distance from the first conductive layer and a third distance from the anode. The second conductive layer is held at a second voltage substantially equal to the voltage of the anode. The first and second openings are chosen based on the first voltage, the second voltage, the first distance, the second distance and the third distance. The opening focuses the electrons emitted from the cathode onto the anode to a spot size preferably less than 40 nanometers. The force created between the cathode and anode is minimized by the structure of the lens.Type: GrantFiled: June 14, 2001Date of Patent: May 25, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Paul J.
