Abstract: 本发明的透射型光电阴极包括以下构成：由金刚石或以金刚石为主要成分的材料形成的光吸收层(1)、增强光吸收层(1)机械强度的支持框(21)、与光吸收层(1)的入射面相对设置的第1电极(31)、以及与光吸收层(1)的出射面相对设置的第2电极(32)。而且，在光吸收层(1)的入射面和出射面之间施加电压在光吸收层(1)内部形成有电场，一旦待检测光入射在光吸收层(1)内部有光电子产生，光电子就因光吸收层(1)内部所形成的电场而在出射面方向上得到加速，从而放射出到透射型光电阴极的外部。

Abstract: 发明公开了一种基于氮化钛材料的新型纳米结构光阴极；所述氮化钛光阴极包括衬底、氮化钛纳米结构层；还涉及了该型氮化钛光阴极的制备方法，及其电场辅助型光阴极测试装置，所述电场辅助型光阴极包括绝缘垫片、金属薄板阳极、上/下电极导线、外加偏压电源。本设计中核心的氮化钛纳米结构具有表面等离激元共振效应，会带来光子吸收增强和局域电场增强，且材料功函数仅约为3.7eV和导电性优良，有助于光致电子的发射；通过设计氮化钛结构的组成纳米图形和结构参数，可获得与入射激励光波相匹配的等离激元共振，实现可光调控的电子发射。因所述氮化钛材料还具有稳定的物化性质，从而本发明提供了一种可作为稳定、高效率的光阴极。

Abstract: A photocathode designs that leverage the grazing incidence geometry yield improvements through the introduction of recessed structures, such as cones, pyramids, pillars or cavities to the photocathode substrate surface. Improvements in yield of up to 20 times have been shown to occur in grazing incidence geometry disclosed herein due to a larger path length of the X-ray photons which better matches the secondary electron escape depth within the photocathode material. A photocathode includes a substrate having a first side and a second side, the first side configured to receive x-ray energy and the second side opposing the first side. A structured surface is associated with the second side of the substrate such that the structured surface includes a plurality of recesses from the second side of the substrate into the substrate.

Abstract: A photocathode which is responsive to ultraviolet light to release photoelectrons includes a supportive window layer of sapphire and a single-crystal active layer of AlGaN. Interposed between the window layer and the active layer is an interface layer which insures a low population density of crystalline defects at the interface of the interface layer with the active layer and in the active layer itself. Consequently, the photocathode is an effective emitter of photoelectrons in the transmission mode.
