Identifying the secondary electron cutoff in ultraviolet photoemission spectra for work function measurements of non-ideal surfaces
Abstract Absolute values of work functions can be determined in ultraviolet photoemission spectroscopy (UPS) by measuring the minimum kinetic energy of secondary electrons generated by a known photon energy. However, some samples can produce spectra that are difficult to interpret due to additional...
