TL;DR: In this paper, a molecular-dynamcis study of silver diffusion in superionic conductor AgI is performed, where the potentials are constructed using Pauling's ideas of ionic radii and the diffusion constant for silver and its temperature dependence are in good agreement with experiment.
Abstract: A molecular-dynamcis study of silver diffusion in superionic conductor $\ensuremath{\alpha}$-AgI is performed. Interionic potentials are constructed using Pauling's ideas of ionic radii. The diffusion constant for silver and its temperature dependence are in good agreement with experiment. Good agreement is also obtained for the silver density map with the experiment of Cava, Reidinger, and Wuensch.

Abstract: The crystal structure of the new fast oxide-ion conductor La2Mo2O9 (ionic conductivity of 0.06 S cm-1 at 800 °C) has been studied. This compound presents a reversible phase transformation around 580 °C from a low-temperature form α-La2Mo2O9 to a high-temperature form β-La2Mo2O9. The high-temperature form β-La2Mo2O9 has a cubic structure (at 617 °C, space group P213; a = 7.2014(5) A; Z = 2; RBragg = 5.8%, Rp = 10.9%, Rwp = 6.5%, χ2 = 7.7) which derives from that of β-SnWO4. Partial site occupation by oxygen atoms, strongly anisotropic thermal factors, and short-range order with a distance characteristic of O−O pairs have been evidenced. An original concept is proposed for the origin of oxide−ion conduction in this compound, which could be applied to the design of new oxide−ion conductors. The low-temperature form α-La2Mo2O9 exhibits a slight monoclinic distortion and a large superstructure relative to β-La2Mo2O9 (2 × 3 × 4), most probably due to the localization of oxygen atoms. The large cell (∼8800 A3) d...
