How can I convert kinetic energy to binding energy while analyzing data from an Ultraviolet Photoelectron Spectroscopy (UPS) measurement?

12 February 2024 1 9K Report

I have data in the form of intensity versus kinetic energy. I need to convert kinetic energy to binding energy. Ultimately, I need to calculate the work function and the position of valence band maximum from the UPS plot.
