Improvements in the contemporary photoemission spectroscopy implementation

Abstract

In this short communication, we revise and refine our previous articles on this topic to simplify the modifications to the angle-resolved photoemission spectroscopy (ARPES) spectrometers required to finally implement our idea, with minimal hardware changes to the spectrometer, if any. Thus, we provide a less cumbersome, practically feasible strategy for verifying changes in the ARPES spectrum using the new photoelectron-detection method. A less cumbersome nature of it should also, in principle, allow us to be able to measure both the ARPES spectra (old as well as new) in one spectrometer for a direct and one-to-one comparison between both the spectra collected under identical (remainder of) experimental conditions. The modifications to the spectrometer are not expected to cause irreparable damage to it; on the contrary, either both could coexist in a single spectrometer, or one could easily revert to the old ARPES from the new one within it, upon choice. Thus, we hereby concretise our proposal.
