Our ordering for Te 3d contains an interesting one, CdTe is a common photovoltaic semiconductor.
CdTe < Te metal < TeO2 < TeCl4 < TeO3
Since Te in CdTe is bonded to cadmium (1.7 on the Pauling scale), it is the more electronegative of the two atoms (2.1 on the Pauling scale). This means, Te will pull electron density towards itself and lower the effective bindign energy below that of Te metal
When sorting these compounds into ascending expected binding energy order, we must consider oxidation state and potential dipoles/electronegativity influences.
For carbon 1s, we have the order:
Metal Carbides (~283 eV), Alkenes (284.8 eV), Alcohols/Ethers (286 eV), Carboxylic Acids (~288.5 eV), Metal Carbonates (~290 eV), Fluorocarbons (294 eV)
In practice, alcohols and ethers are too close to separate, and exactly where the metal carbonate comes will be highly dependant on the metal – so if you’ve assigned these the other way around don’t worry, you’re thinking in the right way!
For Si 2p, we have the order:
Si, Si3N4, Organic Si, Aluminosilicate, SiO2
Hopefully quite straightforward – aluminosilicates, while oxidic in nature as SiO2, introduce a perturbation from Al reducing the binding energy of the Si centres.
For Sulfur 2p we have:
Metal sulfide, Thiol, Elemental sulfur, Sulfonic acid, Metal sulfate
Al ka hv = 1486.7 eV
Mg ka hv = 1253.6 eV
F KLL binding energy with Al ka source = 856.7 eV
F KLL binding energy with Mg ka source = 623.6 eV
F KLL from an Al source will overlap with the Ni 2p peaks at 856 eV, so the best choice is to use an Mg anode
Cu 2p = 932.5 eV
a’ = 1849.4 eV
Species = Cu(I)
Cu LMM auger kinetic energy = 916.9 eV
Al ka source = 1486.7 eV
Cu LMM auger binding energy = 569.8 eV
