摘要： The present invention relates to a photocathode which is applicable to both reflection and transmission types and can yield a quantum efficiency higher than that in a monocrystal diamond thin film, and an electron tube equipped with the same. The photocathode according to the present invention comprises, at least, a first layer made of polycrystalline diamond or a material mainly composed of polycrystalline diamond. In a modified example of the photocathode, the surface of the first layer is terminated with hydrogen or oxygen. Further, a second layer comprising an alkali metal or its compound may be provided on the polycrystalline diamond thin film whose surface is terminated with hydrogen or oxygen.

摘要： The present invention is to provide a method of using a photocathode including a laminated heterostructure of Group III - V semiconductors, which is ccnstituted by a p-type light-absorbing layer formed on a p-type substrate and a p-type electron-emitting layer formed on the light-absorbing layer, a first electrode formed to have a rectifying function with respect to the electron-emitting layer, and a second electrode formed in ohmic contact with the substrate, wherein a voltage necessary and sufficient to form a potential gradient throughout the light-absorbing layer is applied between the first electrode and the second electrode, thereby accelerating photoelectrons excited in the light-absorbing layer which absorbs external incident light on the basis of an electric field formed in the light-absorbing layer and the electron-emitting layer and emitting the photoelectrons from the electron-emitting layer. The accelerated electrons largely decrease differences in transit time until reaching the emission surface of the electron-emitting layer as compared to diffused electrons. Therefore, the response speed of the photocathode for detecting external incident light is increased.

摘要： The present invention relates to an electron tube having a configuration which can maintain its operating stability for a long period of time. The electron tube comprises, at least, a field emitter which is made of diamond or a material mainly composed of diamond and has a surface terminated with hydrogen, and a sealed envelope for accommodating the diamond field emitter. Due to the hydrogen termination, the electron affinity of the diamond field emitter is set to a negative state. Also, hydrogen is enclosed within the sealed envelope. Due to this configuration, the hydrogen-terminated state of the diamond field emitter surface is stabilized, and the electron affinity of the diamond emitter is restrained from changing for a long period of time.
