What is it about?

Nitrogen incorporated Ultrananocrystalline Diamond, (N)UNCD, has been of great interest in recent years for high peak current applications. In this manuscript, we report spectral response in quantum efficiency, photoemission electron energy spectra and mean transverse energy of (N)UNCD photocathode using a photoemission electron microscope.

Why is it important?

This work presents scientific advances that lie at the juncture of photocathode physics, accelerator physics and solid-state physics. Moreover, it will have a direct impact on the choice of the photocathode and the electron gun design of several upcoming accelerator facilities and advancing real world applications like Xray Free Electron Laser and Ultrafast Electron Diffraction and Microscopy Experiments.


This was the first article I wrote during my stint as a Physics PhD student. It was a great experience working with the collaborators and I hope this research paves the way for further research related to ultrananocrystalline diamond photocathodes.
