The characterization of quaternary alloys is a particularly complex task. However, EXAFS is a powerful method, suitable to obtain information about the local atomic structure of a sample and to analyze the ion distributions within any defined configu

A description of the status of the art of experimental and theoretical investigations of local crystalline structures of tetrahedron ordered ternary and quaternary semiconducting alloys is presented. Experimental EXAFS data and FTIR analysis are summ

This manuscript is an attempt to extend the Strained Tetrahedron Model to the interpretation of the EXAFS spectra of Group-IV-IV binary tetrahedron ordered B3 zinc blende alloys. The analysis clearly points out the difference of these systems respect

We discuss x-ray absorption fine structure (EXAFS) data for binary doped CmIm′ compound structures which can be deconvolved to determine elemental bond distances and the deviations from random configurations owing to site preference occupations (SO

Low Temperature Physics. 35:89-93
The local structure of the Ce1−xLaxRu2 system measured by EXAFS is re-examined and correlated to the statistical ad hoc model recently applied to the sphalerite, wurtzite, and other intermetallic ternary alloys. Deconvolution of the EXAFS data show

Tetrahedron coordinated sphalerite quaternary systems of type A 1− x B x Y y Z 1− y consist exclusively of binary and ternary elemental tetrahedra, 4 of the first and 4 of the latter, each 1 with 3 configurations, i.e., a total of 16 elemental te

The statistical strained-tetrahedron model was developed to overcome two common assumptions of previous models: 1) rigid undistorted ion sublattice of regular tetrahedra throughout all five configurations and 2) random ion distribution. These simplif

To understand and interpret the experimental data on the phonon spectra of the solid solutions, it is necessary to describe mathematically the non-regular distribution of atoms in their lattices. It appears that such description is possible in case o

Structural properties of ternary alloys (C1−xC′x)Im depend on relative configuration probabilities that change with the relative content x. Relative configuration probabilities depend on the intensity of site occupation preferences. Several terna
