“…This function takes into account characteristic peaks, bremsstrahlung, and different detection artifacts. Characteristic emission was considered by evaluating the so-called ZAF corrections [atomic number (Z), absorption (A), and fluorescence (F)] with a line profile given by a Voigt function [58], whereas an empirical model was used to fit the bremsstrahlung [59]. For the detection efficiency of the spectrometer, a model developed previously was implemented [60].…”

“…The intensities of the characteristic lines were evaluated by considering the so-called ZAF (atomic number, absorption, and fluorescence) corrections, with line profiles given by Voigt functions [44]. An empirical model was used to describe the bremsstrahlung contribution [45]. The spectra were corrected by the detection efficiency of the spectrometer using a model developed previously [46].…”

Experimental determination of cross sections forK-shell ionization by electron impact for C, O, Al, Si, and Ti

“…where B(E i ) is the function that describes the bremsstrahlung [30], P is the peak intensity of a characteristic K line, H (E i ) accounts for the peak shape function [31], the subindices j , Ox, and subs refer to the elements that compose the films, the oxide layer, and the carbon substrate, respectively. I sp denotes the contribution of spurious radiation (carbon sum peak, escape peaks, and the internal fluorescence peak of the detector) and E is the channel width.…”
