| Outline of Final Research Achievements |
We have developed a new Monte Carlo (MC) simulation code for the quantification of X-ray photoelectron spectroscopy for nano crystals. The time-inverse algorithm of electron creation and transportation was applied to this MC simulation for the purpose of high-throughput calculation to realize good S/N ratio data. This algorithm has already been applied to a homogeneous system previously. It is the first time to apply it to an inhomogeneous system. We successfully developed the new MC code and calculated mean escape depths (MEDs) of 100 eV- 10 keV photoelectrons for Li, C, Si, Cu, Ag, and Au, which have good S/N ratio. The MEDs are useful to estimate coherent lengths of photoelectrons in nano crystals. The data format is also considered to make a database of calculated data.
