The NIST Electron Effective Attenuation Length Database provides values of electron effective attenuation lengths (EALs) in materials at user-selected electron energies between 50 eV and 2,000 eV. The database was designed mainly to provide EALs (to account for effects of elastic-electron scattering) for measurements of the thicknesses of overlayer films and, to a much lesser extent, for measurements of the depths of thin marker layers. EALs are calculated using an algorithm based on electron transport theory for measurement conditions specified by the user. A critical review on the EAL has been published [A. Jablonski and C. J. Powell, Surf. Science Reports 47, 33 (2002)], and simple practical expressions for the EAL, mean escape depth, and information depth are given in another paper by the same authors [J. Vac. Sci. Technol. A 27, 253 (2009)].
