The atomic motions in crystals are correlated. In this paper we demonstrate that information about the correlated motion of atoms, and consequently about the bonding within the crystal, can be obtained by analyzing the peak width of the atomic pair distribution function (PDF). We have measured the PDFs of Ni and InAs using synchrotron X-ray diffraction. The analysis of the Ni data allowed us to determine the Debye temperature which is in good agreement with values found in the literature. In contrast to the isotropic metallic bonding in Ni resulting in a relatively weak correlation between the motion of neighboring atoms, we found a very strong correlation in InAs as one might expect from the covalent bond between In and As. The results are compared with theoretical predictions by Chung and Thorpe (Phys. Rev. B 1977, 55, 1545).

“…In recent years, an analysis technique that does summation over vibrational modes has been developed that can give extremely good agreement between calculated and experimental PDFs for crystalline materials with no static local distortions 4–6. In this method, under assumptions that lattice constants are known, it was shown that one or two spring constants that correspond to the bond‐stretching and angle‐bending are sufficient to reproduce very accurately the widths (positions are known) of the PDF peaks up to the distances ∼20Å in materials like InAs and Ga 0.5 In 0.5 As 7…”

The volume, I believe, reaches far more than scholars in technology studies or development studies. It should appeal to people working in various disciplines such as media studies, sociology, women's studies, and cultural studies because human rights is central to each of them. The volume will help give the disciplines a necessary spin in the era of heightened technocapitalism and informatization.
