With a unique set of electronic states, each element has its own "finger-print" in the XPS spectrum. Each electronic state is occupied by electrons with a specific binding energy. In the spectrum above, the dominant peaks of carbon, oxygen and silicon are seen. | With a unique set of electronic states, each element has its own "finger-print" in the XPS spectrum. Each electronic state is occupied by electrons with a specific binding energy. In the spectrum above, the dominant peaks of carbon, oxygen and silicon are labelled. More peaks are seen in this socalled survey spectrum but they are all associated to these three elements. With its wide energy range, the survey spectrum ing energies will show the | ||
