    Abstract: The inventive method for extracting electrons in a vacuum consists in the following: creation of a cathode which comprises at least one junction (9) between a metal (7) which is used as an electron reservoir and an n-type semiconductor (8), possessing a surface potential barrier which has a height which is measured in tenths of electron volts and having a thickness ranging from 1-20 nm; the electrons are injected via the metal-semiconductor junction (9) in order to create a charge which has enough space to reduce the semiconductor surface potential barrier to a value which is lower than or equal to 1 eV in relation to the Fermi level of the metal (7); the height of the n-type semiconductor surface potential barrier (Vp) is controlled with the aid of the polarization source creating an electric field in a vacuum in order to regulate emission of the electron flow to the anode.

    Abstract: A planar doped barrier region of semiconductor material is coupled to a vacuum or gaseous region to provide electron emission from the planar doped barrier region into the vacuum or gaseous region. When a voltage is applied across the planar doped barrier region electrons flow from one end of the region to another. This flow results in the emission of electrons if the work function of the emission surface is less than the handgap of the semiconductor material. The device of the present invention can be used as a vacuum microelectronic emitter, a vacuum microelectronic transistor, light source, klystron, or travelling wave tube.

    Abstract: In a flat panel display or other type of electron device, a thin-film electron emitter (51) and/or emitter array (50) is formed in a semiconductor film (10) of, for example, hydrogenated amorphous and/or microcrystalline Si, SiCx, SiNy, SiOxNy or the like. An injector electrode (14) forms a potential barrier ( PHI B) with the semiconductor film (10) at a back major surface (12) of the film (10). A front electrode (15) serves for biasing an emission area (11a) of the front major surface (11) at a sufficiently positive potential (V15) with respect to the injector electrode (14) as to inject electrons (e) over the barrier ( PHI B) in the operation of the emitter (51) while controlling the magnitude of an electron accumulation layer (Ne) in the semiconductor film (10) at the emission area (11a). Under this bias condition the semiconductor film (10) supports a depletion layer from the injector electrode (14) to the electron accumulation layer (Ne), so establishing a field in which the electrons are heated and directed towards the emission area (11a). The electron emission area is a plane surface area (11a) free of the front electrode (15), to which it may be connected directly or by a gateable connection (G, 29). Some of the electrons from the injector electrode (14) are emitted at the emission area (11a), while others heat electrons in the accumulation layer (Ne) to stimulate their emission. The front electrode (15) extracts excess electrons not emitted from the emission area (11a). The emitter (51) is well suited for fabrication with thin-film silicon-based technology.
