When a photoemission event takes place, the following energy conservation rule holds: where is the photon energy, is the electron BE (binding energy with respect to the vacuum level) prior to ionization, and is the kinetic energy of the photoelectron. If reference is taken with respect to the Fermi level (as it is typically done in photoelectron spectroscopy) must be replaced by the sum of the binding energy (BE) relative to the Fermi level, , and the sample work function, .

WebDec 7, 2024 · The effect of thermal broadening on the linewidth of core level and valence band spectra was explored for a series of alkali metal halides: CsF, CsI, NaF, NaI and related compounds. Variation in temperature from -100 °C to +100 °C led to changes in the linewidths for both core level and valence band spectra.

WebOct 6, 2024 · The objective of curve-fitting high-resolution core XPS spectra with a set of component peaks is to separate the photoemission signal originating from distinct elemental or chemical states. Parameters of importance extracted from curve fitting are the photoemission peak BE, full width at half maximum (FWHM), lineshapes, and area. http://rsl.eng.usf.edu/Documents/Tutorials/PEScalibration.pdf rock cottage leinthall earls
