High-current electron field emitters are of interest for many applications, but state-of-the-art devices suffer from limitations such as high turn-on macroscopic field, low macroscopic current density, poor emission stability, and short lifetime. Field emitter arrays with a high spatial density of uniform emitters have the potential to address these problems. This work presents the process development, fabrication, and testing of a novel field emitter array. The authors employed electron beam lithography and templated electrodeposition to fabricate a high spatial density array of metallic nanowires, resulting in electron emission with high macroscopic current density (2 A/cm2) and low turn-on macroscopic field (4.35 V/μm). Templated electrodeposition of metallic nanowire arrays is a promising method for producing high performance field emitters.

来自电沉积金属纳米线阵列的高电流密度电子发射

高电流电子场发射器在许多应用中受到关注，但最先进的设备受到诸如高开启宏观场、低宏观电流密度、发射稳定性差和寿命短等限制。具有高空间密度的均匀发射器的场发射器阵列有可能解决这些问题。这项工作介绍了新型场发射器阵列的工艺开发、制造和测试。作者采用电子束光刻和模板化电沉积来制造金属纳米线的高空间密度阵列，从而产生具有高宏观电流密度 (2 A/cm2) 和低开启宏观场 (4.35 V/μm) 的电子发射。金属纳米线阵列的模板电沉积是一种生产高性能场发射器的有前途的方法。
