Abstract
The temperature dependencies of the electrical conductivity and dielectric permittivity of (BS)(1-x)(DAsS2)(x) (B = Ge, Ph; D = Ag, Cu) were investiga ted by means of impedance measurements in the frequency range between 10(-1 ) and 10(5) Hz and at temperatures between 78 and 500 K. In all chalcogenid es, ionic conductivity (Ag+ or Cu+) was found. The onset of ionic transport was found at 115-120 K for AgGeAsS3 and 110-115 K for CuGeAsS3. The comple x impedance and admittance plots, the electrical properties and the X-ray s tructure data are given. (C) 1999 Elsevier Science B.V. All rights reserved .
