Abstract: A surface with a low work function is formed from a starting material of diamond or diamond-like carbon. An oxygenation treatment is performed, so that the surface of the diamond or diamond-like carbon is oxygenated. Lithium is then deposited onto the oxygenated surface by means of a physical vapour deposition process. Excess lithium is then removed to form a lithium monolayer.

Abstract: An automatic locking ball coupler for a power take off includes a ball keeper connected to the power take off and having a longitudinal axis and openings in a cylindrical surface thereof. Locking balls are received in the openings and can move radially with respect to the axis of the cylindrical ball keeper. A ball collar is positioned around the cylindrical ball keeper and has a plurality of internal circumferential rings and recesses between each ring. The ball collar can slide axially with respect to the longitudinal axis of the ball keeper between a coupled position in which the locking balls are on the rings and an uncoupled position in which the locking balls are in the recesses.

Abstract: An electron emitter including a high work function metal 18 encapsulating a metal-doped, nanocrystalline diamond particle layer 14 in contact with a planar surface of a low workfunction metal cathode 12, and a method of fabrication of the same is disclosed. The method may include formulating the conductive nanodiamond powder with a metallic solution, containing the high workfunction metal, and disposing it on the metal cathode 12 to form a composite material layer containing surface areas exhibiting low electron affinity. The resulting cold cathode structure has a low extraction field needed for efficient emission, a means to limit the emission current per unit area, and a reduced emission sensitivity to surface adsorption/desorption effects.

Abstract: A monolithically integrated circuit arrangement is arranged in a disc-shaped monocrystalline semiconductor body (100) of a first conductivity type, which semiconductor body consists of silicon and has a first and second main surface.
