Methods using low energy photoemission, such as photoelectron spectroscopy, constant-final-state photoelectron yield spectroscopy, and photoelectron yield spectroscopy, as a tool to examine the density-of-states (DOS) of materials will be discussed. In particular, the validity of the analysis method for estimating DOS using the differentiation of the yield spectrum of photoelectron yield spectroscopy will be discussed based on the measurement results of the gold thin film.
