QUASES-Inelastic electron mean free path calculator (by TPP2M formula)

Research output: Non-textual formComputer programmeCommunication


The QUASES-IMFP-TPP2M-CF software is a user friendly calculator for the inelastic electron mean free path for electrons in materials. It is based on the Tanuma, Powell and Penn algorithm [1,2].

The software includes a database with parameter values for all elements and a wide range of compounds, oxides, and polymers. There are also facilities to easily expand the database with new materials.

The software also provides means to calculate the elastic scattering correction in XPS. The change in XPS peak intensity from a layer of atoms at depth z, caused by elastic electron scattering, is conveniently described by a correction factor CF, which can be estimated with the software within two approximations [3,4,5].

A manual is integrated in the software.
