Thin PMMA films were investigated by high- and standard-resolution XPS and variable-angle NEXAFS. The results of fitting of the respective C 1s and O 1s XP spectra are compared with the latest literature data. It is found that using a non-constrained “1:1:1:2” fitting strategy good agr...

with an average diameter of 2.17 nm. The appearance of a shake-up peak and C–C and C=C bonding peaks in the C1s XPS spectra confirmed that the quality of the graphene structure improved with increasing hydrothermal reaction time. Moreover, the XPS results revealed that C–N species su...
The XPS evaluation of C sp2/sp3 hybridisations utilises either the C 1s spectra fitting and/or X-ray excited Auger spectra (XAES C KVV or C KLL). However, several problems with determination of carbon coordination values exist and therefore they may be burdened with a statistical and systema...
