This Small Business Innovation Research Phase II project addresses scaled up production of high quality carbon nanotube (CNT) field emitters, which are promising electron sources that can potentially overcome the limitations of thermionic source based devices. The current commercially available CNTs have limitations in terms of field emission performance, thermal stability and cost. Xintek and its collaborators at Duke University developed a proprietary few walled carbon nanotubes (FWNTs) which is shown to possess superior field emission performance compared to other commercially available CNTs. Upon the successful completion of the Phase II project, the low cost high quality field emission FWNTs will be produced to deliver improved field emission performance for a broad range of applications including but not limited to field emission displays, X-ray sources, vacuum electronic devices, accelerator electron guns, and high current electron beam processing facilities.

这个小型企业创新研究第二阶段项目解决了高质量碳纳米管（CNT）场发射体的规模化生产，这是有前途的电子源，可以克服基于电子源的设备的局限性。目前市售的CNT在场发射性能、热稳定性和成本方面具有局限性。Xintek及其合作者在杜克大学开发了一种专有的几壁碳纳米管（FWNTs），与其他市售的CNT相比，它具有上级场发射性能。第二期项目成功完成后，将生产低成本高品质场发射FWNT，以提供更佳的场发射性能，应用于广泛的应用，包括但不限于场发射显示器、X射线源、真空电子器件、加速器电子枪及高电流电子束处理设施。
