EXAFS analysis of negative expansion

An interesting paper has been published showing the extended X-ray absorption fine structure (EXAFS) as evidence of negative expansion of CdTe crystal. Measurements were done for both the K edges of cadmium and tellurium, from 4.2 K to room temperature. For more information, see the papers, "Negative thermal expansion in crystals with the zincblende structure: an EXAFS study of CdTe", N Abd el All et al., J. Phys.: Condens. Matter 24, 115403 (2012).
