046: XPS for Beginners – Data Analysis 6

In data analysis 6 – we look at peak asymmetry, and how we account for this in our peak models.

To remind yourself of how asymmetry arises – go back to the fundamentals 5 session or check out our guru page for a refresher!

Tips:

Start with graphene to get used to the parameters

For Fe metal – just try and fit the 2p3/2 – this region has a steep background

Don’t forget about the plasmons that may appear!

Ta metal vs Oxide will be a test of using your lineshapes in a model fit. Remember – the oxide peaks here are not asymmetric! Fit the metal only first and use this to inform the metal + oxide model. Don’t forget about the 5p peak present (use the element library (F10) to identify rogue peaks).

Why not check out our guru page on lineshapes as a handy side-guide to fitting asymmetric peaks?
