Electron emitter devices are used in a broad range of applications including RF amplifiers for communications and RADAR. Increasing need for global communications driven by market demand for live, streaming video quality data for mobile users is limited by existing infrastructures and technologies. Travelling wave tubes (TWTs) remain an important enabling technology for this sector, creating RF amplification for communications at greater than double the efficiencies that the best compound semiconductors have been able to deliver. However, TWTs are currently constrained to thermionic electron sources that intrinsically limit lifetime. Diamond semiconductors offer strong potential due to their high electron mobilities and excellent thermal properties; however they have been limited in applications due to the difficulty in producing commercially viable p-n semiconductor junctions. The REDEFInE project, redefines electron field emitters by creating novel diamond electron emitters embedded into intrinsic diamond to create optimal thermal management with no inherent wear mechanisms.

电子发射器的应用范围很广，包括通信和雷达用的射频放大器。移动用户对实时、流媒体视频质量数据的市场需求推动了对全球通信日益增长的需求，但现有基础设施和技术限制了这一需求。行波管(行波管)仍然是这一领域的重要推动技术，为通信创造射频放大的效率是最好的化合物半导体所能提供的效率的两倍以上。然而，行波管目前被限制在本质上限制寿命的热离子电子源。金刚石半导体具有很高的电子迁移率和优异的热性能，具有很强的潜力；然而，由于难以制造商业上可行的p-n半导体结，它们的应用受到了限制。重新定义项目，通过创建嵌入到固有钻石中的新型钻石电子发射器来重新定义电子场发射器，以创建没有固有磨损机制的最佳热管理。
