Abstract: PROBLEM TO BE SOLVED: To form a flat emission device having a large current density and to ensure an operation in an environment of a low degree of vacuum. SOLUTION: The emission device (50, 100) has an electron supply source (10) and a porous cathode layer (14) having a nanohole opening (22). Further, the emission device has also a tunnel layer (20) arranged between the electron supply source and the cathode layer. COPYRIGHT: (C)2004,JPO

Abstract: An antireflection surface formed using a plurality of nanostructures of a first material on a surface of a second material. The first material is different from the second material. The distribution of spatial periods of the nanostructures is set by a self-assembly operation. The surface of the second material is converted to operate as a graded index surface that is substantially antireflective for the wavelength of interest.

Abstract: A method is disclosed for creating an emitter having a flat cathode emission surface: First a protective layer that is conductive is formed on the flat cathode emission surface. Then an electronic lens structure is created over the protective layer. Finally, the protective layer is etched to expose the flat cathode emission surface.

Abstract: An emitter has an electron supply layer and a tunneling layer formed on the electron supply layer. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within in which the tunneling layer is formed. A cathode layer is formed on the tunneling 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.
