Structure-Function Relationships in Fast Copper Ion Conductors<br /> Crystalline superionic conductors of copper iodide (CuI) and Rb<small>4</small>Cu<small>16</small>I<small>7</small>Cl<small>13</small> with cubic symmetry have been investigated using time-of-flight (TOF) neutron powder diffraction techniques at KEK Neutron Science Laboratory, Japan. The aim has been to clarify the ionic conduction mechanism in the fast copper ions conductors. Conventional Rietveld method and the Maximum Entropy Method (MEM) have been used extensively to analyze the crystal structure and to visualize the nuclear density distribution of the both systems. Local structure analysis of CuI was carried out by means of the Pair Distribution Function (PDF) and the Reverse Monte Carlo (RMC) to modeling the mobile copper ions disorder. For CuI system, the results suggest that the most possible conduction pathways inside the one unit cell are along <001> directions, with local Cu-Cu correlation observed between the neighboring tetrahedral <i>8c-32f</i> sites and neighboring tetrahedral <i>32f-32f</i> sites, as represented by the split atom model in the space group <i>Fm-3m</i>. For Rb<small>4</small>Cu<small>16</small>I<small>7</small>Cl<small>13</small> system, the results reconfirm that copper ions at Cu(1) and Cu(2) sites that moving at temperature above 100 K along the pathways of －Cu(1)-Cu(2)-Cu(1)- play the important role for increasing the total conductivity in the Rb<small>4</small>Cu<small>16</small>I<small>7</small>Cl<small>13</small> system. |
