Geochemistry Mineralogy Ag isotope fractionation superionic conduction mineral aggregate growth conductive bridging random access memory An unusual metal isotope fractionation has been observed in association with the growth of wire silver, whose unique texture and morphology can be explained by superionic conduction of Ag<sup>+</sup> in Ag<sub>2</sub>S. This constitutes the first recognition of mass migration by fast ion conduction in nature. Stable Ag isotope analysis revealed natural wire silver is normally enriched in the heavy isotope <sup>109</sup>Ag, while common fractionation mechanisms would predict the opposite. In synthetic wires grown at high temperature (>450°C), this fractionation is amplified by an order of magnitude more than expected by any known isotope effect. This may indicate a previously unrecognized isotope fractionation mechanism associated with superionic conductors in nature and in general, which would have important implications for the geochemistry of ore deposits, as well as fast-ion technologies including atomic switches and solid-state ion batteries. 2018-07-30 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1532606440752015 http://rave.ohiolink.edu/etdc/view?acc_num=miami1532606440752015 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
