The Elements & Native Oxides
Includes wide scan spectra and high energy resolution spectra for the elements Ag, Al, Ar(+), As, Au, B, Ba(+), Be, Bi, Br (-), C, Ca (2+), Cd, Ce (4+), Cl (-), Co, Cr, Cs (+), Cu, Dy, Er, Eu, F (-), Fe, Ga, Gd, Ge, Hf, Hg, Ho, I (-), In, Ir, K (+), La (3+), Li (+), Lu, Mg, Mn, Mo, N (3-), Na (+), Nb, Nd, Ni, O (2-), P, Pb, Pd, Pr, Pt, Rb (+), Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr (2+), Ta, Tb, Te, Ti, Tl, Tm. V, W, Xe (+), Y, Yb, Zn, and Zr. All surfaces were cleaned by using practical methods. All high energy resolution spectra are peak-fitted to reveal FWHM, and peak separation for spin-orbit pairs. The strong signals observed in the wide scan spectra are labeled and tabulated together with rough BE values of those strong signals. The BEs of the high energy resolution spectra in this handbook were used as part of a recent NIST study to determine "reliable" binding energies of the principal XPS signals of each element (C.J.Powell, Applied Surface Science, Vol. 89, pp 141-149, 1995.)
The Native Oxides:
Includes wide scan spectra, and principal signal high energy resolution spectra, carbon (1s) high energy resolution spectra, and oxygen (1s) high energy resolution spectra found, as received, in/on the naturally formed, native oxides of the elements Ag, Al, As, B, Be, Bi, Cd, Co, Cu, Fe, Ga, Ge, Hf, In, Ir, Mg, Mn, Mo, Nb, Ni, Pb, Pd, Pt, Re, Rh, Ru, Sb, Sc, Se, Sn, Ta, Te, Ti, Tl, V, W, Y, Zn, and Zr. Atomic percentage tables of surface composition are provided. These spectra reveal the natural oxidative tendencies of the elements and the tendencies of these elements to capture various gases from the air and/or various contaminants introduced to the surface from handling by the original chemical producers. No attempt was made to clean these samples.
Includes wide scan spectra, principal metal signal high energy resolution spectra, some secondary metal signal high energy resolution spectra, carbon (1s) high energy resolution spectra, oxygen (1s) high energy resolution spectra, valence band spectra, Auger signal spectra,a dn atom % data obtained from the following semiconductors that were analyzed "as received" and "after freshly exposing the bulk" by fracturing in air. Some materials were analyzed "after ion etching" or "chemical cleaning".

Includes wide scan spectra, and >15 repetitive cycles of high energy resolution carbon (1s) spectra, high energy resolution oxygen (1s) spectra, other principal signal high energy resolution spectra, and atom % data tables from polymers known as: poly-acetal, poly-acrylonitrile (PAN), poly-amide, poly-1-butene, poly-caprolactam (nylon 6), poly-carbonate bis-phenol A (PC), poly-ethylene (HDPE), poly-ethylene oxide (PEO), poly-ethylene terephthalate (PET), poly-imide (Kapton), poly-methylmethacrylate (PMMA), poly-4-methyl-1-pentene, poly-phenylene sulfide (PPS), poly-propylene (PP), poly-styrene (PS), poly-sulfone resin, poly-tetrafluoroethylene (PTFE), poly-vinyl acetate (PVA), poly-vinyl chloride (PVC), poly-vinylidene fluoride, and nitrocellulose. Each sample was analyzed overnight for >12 hours to observe the X-ray induced changes that occur from extended exposure to X-rays. Overlays of the initial and final state spectra, which reveal the degree and nature of the degradation caused by the long term exposure, are included.
