What is Refinements of Ag3AsSe3based on high-order thermal-motion tensors about?
Ag3AsSe3; rhombohedral, R3c, ahex = 11.299 (2), chex = 8.759(3) Ä, c/a = 0.7752, Z = 6, is composed of the trigonal pyramids of AsSe3 and Ag atoms, which weakly link the AsSe3 groups. High-order thermal-motion tensor analyses of Ag3AsSe3, based on the Gram-Charlier expansion, have shown that the density distribution of Ag is well expressed by a combination of the first-, the second-and the third-order tensors. The density distribution of Ag is unimodal but strongly distorted from that expected for harmonic vibrations: it occupies a platy region, and tails off long toward three neighboring interstitial sites, each of which is located at about equal distances from the three nearest Ag atoms. The thermal vibrations of other atoms are of much smaller amplitudes than those of Ag, and can be well approximated by harmonic motions.
Who reads Refinements of Ag3AsSe3based on high-order thermal-motion tensors?
It is typically read by researchers, students, and practitioners in Materials Science.
