Ionic conductivity in AgAsS2 has been measured at 20-600 degrees C for crystalline, glassy, supercooled, and liquid states. The liquids possess substantially smaller activation energies (similar to 02 eV) and conductivity prefactors (similar to 3 S/cm) than those in the solids. Other electrical characteristics are discussed, taking calorimetric and dilatometric results into account. (C) 2014 Elsevier B.V. All rights reserved.
