Research

My research is focused on the growth and characterisation of next generation photocathodes, namely ultra thin metal oxides films. This project seeks to improve the quantum efficiency (QE), the number of electrons emitted per incident photon, of the photocathodes. These photocathodes will be considered for both accelerator and UV sensor applications, ultimately improving the performance (emittance, response time and durability) compared to conventional metal photocathodes.

I use a variety of techniques to characterise samples including Kelvin Probe, X-ray Photoelectron Spectroscopy (XPS), UV Photoelectron Spectroscopy (UPS) and QE measurements.
