88. RMC is 35 – How has it changed total scattering/pair distribution function analysis?

When the original Pusztai & McGreevy RMC paper was published in 1988
we were at a turning point in the use of total scattering and pair
distribution functions (PDFs) in structural analysis. This talk examines
to what extent their paper was a watershed, transforming not just total
scattering analytical methods but also the way that we thought about
structure, and disordered structure in...

Talks

Te-rich amorphous Ge-Sb-Te alloys were investigated by diffraction techniques and EXAFS. Structural models were obtained by fitting all datasets (5 for each sample) simultaneously. The results showed that the alloys are chemically ordered (number of heteronuclear bonds maximized) and obey the 8-N rule. An overview of literature data shows a strong correlation between the glass transition...

60. Advances in modelling X-ray absorption spectroscopy data using reverse Monte Carlo

Modern extended X-ray absorption fine structure (EXAFS) analysis is based on multiple-scattering calculations. Those calculations are carried out for fixed atomic configurations and proper account of the thermal and static disorder, corresponding to well-defined pair and higher-order distribution functions, can be obtained using different methods. The application of the Reverse Monte Carlo...
