C1s Peak Fitting Tutorial - Not a straightforward example

Описание: In this video, I made a C1s peak fitting. Sample is an carbon fabric electrode and includes organic binders. It is electrically conductive, so we do not have a charging issue. By using CasaXPS, I tried to make a proper C1s peak fitting. Due to the limitted information about the sample, peak fitting is open to discussion.
