SBIR Phase II: Efficient Production of High Quality Carbon Nanotube Field Emitters

这个小型企业创新研究第二阶段项目致力于大规模生产高质量的碳纳米管（CNT）场发射器，这是一种有前途的电子源，可以潜在地克服基于热离子源的设备的局限性。目前市售的碳纳米管在场发射性能、热稳定性和成本方面存在局限性。Xintek及其在杜克大学的合作者开发了一种专有的少壁碳纳米管（FWNTs），与其他市售碳纳米管相比，该碳纳米管具有优越的场发射性能。在第二期项目成功完成后，将生产低成本高质量的场发射FWNTs，为广泛的应用提供更好的场发射性能，包括但不限于场发射显示器，x射线源，真空电子设备，加速器电子枪和大电流电子束处理设施。

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.
