Asymmetry

 



 

Using Asymmetry for Peak-fitting

 

Example #1:  Aluminum (Al) metal – Al (2p3) & Al (2p1)

 



 

Neal Fairley’s Peak-fit of Al (2p) using CasaXPS

using a convoluted hybrid of Doniach-Sunjic peak shape and Gaussian-Lorentzian.

 



 

 

Example #2:  Asymmetry in Manganese and Chromium

 

Cr normal size

Mn normal size

Fe normal size
