Overview
Each page provides XPS spectra from a series of materials: pure element, native oxide, most common pure oxide, and other chemical compounds that may include hydroxide, oxy-hydroxide, carbonate, bi-carbonate, sulfide, sulfate, nitride, nitrate, phosphide, phosphate, selenide, telluride. Most of the oxides are single crystals or natural crystals freshly cleaved to expose bulk. Semiconductor wafers and crystals have been cleaved to expose bulk. There are time-based Profiles, Flood Gun tests, and Auger spectra. To add a bit of color, there are two sets of photos from crystals that include the element being displayed. A total of six (6) different BE tables from various sources are included. The Spectra-Base currently (Jan 2025) has:-
-
- >500 survey spectra,
- >2,500 chemical state spectra,
- >2,500 peak-fits of chemical state spectra,
- >600 overlays of chemical state spectra,
- >400 side-by-side comparisons of chemical state spectra.
- >150 time study Montage plots showing UHV gas capture by freshly ion etched metals,
- >150 overlays showing flood gun effects on native oxides
- >200 photos of minerals containing element of interest
- >90 tables of key information listing peak overlaps, spin-orbit terms, BEs, Scofield cross-sections and IMFP of pure element
- >500 tables of BEs (from 6 different sources)
