Abstract: The work function of electron emitters can be modified by forming a modifying layer at the surface using low energy ion implantation, in a controlled environment, placing chosen elements below the surface of electron emitters as Cs implanted in Si(100) at four different doses illustrates. Sometimes implanted species are deep enough that they do not react with the atmosphere during subsequent low-temperature processing. Then, species implanted in the emitting surfaces are segregated using elevated temperature treatment of the emitters in vacuum and/or reactive gases. The implanted ions modify the work function at the surface, via thin layers of the implanted species on top of the emitter surfaces, or compounds or alloy layers at the surface of the emitters. Depending on the implanted species, the initial emitter material, and the environment, these layers can either increase or decease the work function of the emitter.

Abstract translation: 电子发射体的功函数可以通过在受控环境中使用低能离子注入在表面上形成修饰层进行修饰，将选定的元素放置在电子发射体的表面以下，以四种不同剂量注入Si（100） 。 有时植入的物种足够深，以至于在随后的低温处理过程中它们不会与大气反应。 然后，通过在真空和/或反应气体中对发射体进行高温处理，将注入发射表面的物质分离。 注入的离子通过在发射体表面顶部的注入物质的薄层，或在发射体的表面处的化合物或合金层来修饰表面的功函数。 根据植入物种，初始发射体材料和环境，这些层可以增加或降低发射体的功函数。

Abstract: A matrix addressable flat panel display includes a flat cathode (31) operable for emitting electrons to an anode (15) when an electric field is produced across the surface of the flat cathode by two electrodes (34) placed on each side of the flat cathode. The flat cathode (31) may consist of a cermet or amorphic diamond or some other combination of a conducting material and an insulating material such as a low effective work function material. The electric field produced causes electrons to hop on the surface of the cathode (31) at the conducting-insulating interfaces. An electric field produced between the anode (15) and the cathode (31) causes these electrons to bombard a phosphor layer (16) on the anode (15).

Abstract: A cathode structure contains electronegative matter (22), which consists of oxygen and/or fluorine, chemically bonded to a carbon containing cathode (10). The bonding is accomplished by subjecting carbon-containing cathode to the electronegative matter in dissociated form using a technique such as a plasma. Electropositive metal (24R) is chemically bonded to the electronegative matter. The combination of the electropositive metal and electronegative matter enhances the electron emissivity by reducing the work function.
