    Abstract: In an embodiment, a method includes forming a first diamond layer (250) on a substrate (210) and inducing a layer of graphene (260) from the first diamond layer (250) by heating the substrate (210) and the first diamond layer (250). The method includes forming a second diamond layer (270) on top of the layer of graphene (260) and applying a mask to the second diamond layer (270). The mask includes a shape of a cathode, an anode , and one or more grids. The method further includes forming a two-dimensional cold cathode (220), a two-dimensional anode (230), and one or more two-dimensional grids (240) by reactive-ion electron-beam etching. Each of the two-dimensional cold cathode (220), the two-dimensional anode (230), and the one or more two-dimensional grids (240) includes a portion of the first diamond layer (250), the graphene layer (260), and the second diamond layer (270) such that the graphene layer (260) is positioned between the first diamond layer (250) and the second diamond layer (270).

    Abstract: An X-ray tube, a medical X-ray device comprising such X-raytube and a method for operating such X-ray tube are proposed. The X-ray tube (1) comprises an electron emitter (3) with a substrate (4) having an electron emission surface (5). The electron emission surface (5) is adapted for field emission of electrons therefrom by providing a substantial roughness. Such roughness may be obtained by applying carbon nano-tubes (19) onto the electron emission surface (5). A field generator (7) is provided for generating an electrical field adjacent to the electron emission surface (5) for inducing field emission of electrons therefrom. Furthermore, a heater arrangement (15) is provided and adapted for heating the electron emission surface (5) contemporaneous with the field emission of electrons. Accordingly, while electrons are emitted from the electron emission surface (5) due to a field effect, this electron emission surface (5) may also be heated to substantial temperatures of between 100 and 1000°C. It has been observed that such heating may stabilize electron emission characteristics as the emitter (3)as adsorbents or contaminations to the carbon nano- tubes may be reduced.

    Abstract: The invention relates to a method for making a cathode-luminescent capsule (1) that comprises at least one housing (10), a cold cathode (20), an anode (30) and a gate (40). The method at least comprises the steps of: depositing (A) phosphor (50) and reflective (60) layers on an inner wall (101); depositing (B) a conducting layer (70) at least in contact with the phosphor layer; making (C) a base (80) with a tube (90) including at least three metal conductors each respectively welded to the anode, the cathode and the gate; assembling (D) the base with the housing in order to form the capsule, the anode in contact with the conducting layer and the phosphor layer opposite the cathode; placing the capsule under vacuum (E) via the tube; and sealing (F) the capsule by closing an end of the tube of the base.

    Abstract: A CNT electron source, a method of manufacturing a CNT electron source, and a solar cell utilizing a CNT patterned sculptured substrate are disclosed. Embodiments utilize a metal substrate which enables CNTs to be grown directly from the substrate. An inhibitor may be applied to the metal substrate to inhibit growth of CNTs from the metal substrate. The inhibitor may be precisely applied to the metal substrate in any pattern, thereby enabling the positioning of the CNT groupings to be more precisely controlled. The surface roughness of the metal substrate may be varied to control the density of the CNTs within each CNT grouping. Further, an absorber layer and an acceptor layer may be applied to the CNT electron source to form a solar cell, where a voltage potential may be generated between the acceptor layer and the metal substrate in response to sunlight exposure.
