XPS Spectra
Silicon (Si) Compounds
The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra.
Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.
Peak-fits are guides for practical, real-world applications. Peak-fits are not fully optimized or designed to test any theory.

NIST Composition Tables for SRM 614

Preparation and Analysis: Sixty-one trace elements were added to the glass support matrix, which has a nominal composition of 72 % SiO2, 14 % Na2O, 12 % CaO, and 2 % Al2O3 (mass fractions). A list of 29 elements that were added but for which no values have been assigned is provided in Table 4. The material was prepared in rod form and then sliced into wafers. Considerable effort was invested in the manufacturing of the material to ensure sufficient homogeneity to yield a ≤2 % relative repeatability of measurement when an entire wafer is used. Spatial heterogeneity exists within each wafer, which may adversely affect repeatability of microanalysis techniques. Values were assigned using the analytical methods listed in Table 5.



A nominal composition of:

72 % SiO2, 14 % Na2O, 12 % CaO, and 2 % Al2O3 (mass fractions).
