Calculation of inelastic mean free path of photoelectrons in some solids

Calculations of electron inelastic mean free paths. XII. Data for 42 inorganic compounds over the 50 eV to 200 keV range with the full Penn algorithm

“…We also report comparisons of our calculated IMFPs for the 42 inorganic compounds with IMFPs calculated by Reich et al Akkerman et al Pandya et al Kwei and Li, Kwei et al Boutboul et al Ashley and Anderson, Dapor and Miotello, and Dapor, and with IMFPs measured by Iakoubovskii et al Egerton, Meltzman et al Gurban et al Pi et al Krawczyk et al Chung et al Wang and Shapiro, McCartney and Gajdardziska‐Josifovska, Lee et al and Bideux et al Zommer et al and Jung et al We also make comparisons between the measured IMFPs and IMFPs from the relativistic TPP‐2M equation.…”

“…Figure shows comparisons of our IMFPs with IMFPs calculated for Al 2 O 3 , GaAs, KBr, KCl, MgO, NaCl, and SiO 2 for energies between 10 eV and 10 keV. We have plotted the IMFP data in the literature, listed above, in Figure without any energy‐scaling corrections.…”

“…The solid lines show our IMFPs that were calculated from optical ELFs with the FPA. The symbols indicate IMFPs calculated by Reich et al (for Al 2 O 3 and SiO 2 ), Akkerman et al (for Al 2 O 3 , KBr, KCl, MgO, and SiO 2 ), Pandya et al (for Al 2 O 3 and SiO 2 ), Kwei and Li (for GaAs), Boutboul et al (for NaCl), Kwei et al (for MgO, glassy SiO 2 and crystalline SiO 2 ), Ashley and Anderson (for SiO 2 ), Dapor and Miotello (for Al 2 O 3 , MgO, and SiO 2 ), Dapor and Miotello (for SiO 2 ), and Dapor (for SiO 2 )…”

“…Reich et al calculated IMFPs for Al 2 O 3 , SiO 2 , and GeO 2 in 1988 for energies from 200 to 3700 eV using an independent atomic‐center approximation. The total inelastic‐scattering cross sections of O, Al, Si, and Ge atoms were calculated within the framework of the Born approximation with consideration of both ionization processes and excitation to discrete levels.…”

Single-crystal and polycrystalline diamond erosion studies in Pilot-PSI

“…While the shape of the diamond sp 3 peak remains unmodified for both samples in Figure 6, the peak of sp 2 is more pronounced for the exposed sample; sp 2 /sp 3 ratio raised from 0.018 to 0.34 after exposure. Inelastic mean-free-path of 1.2 keV photoelectrons in amorphous carbon is 2 nm [31], which means that 65% of the measured signal originates from the topmost 2 nm Table 2. The ratio of sp 2 to sp 3 hybridization of C atoms and the quantity of oxygen measured by XPS.…”
