Abstract

The crystal structure of Ag7(Si0.8Ge0.2)S5I, Ag7(Si0.6Ge0.4)S5I, Ag7(Si0.4Ge0.6)S5I and Ag7(Si0.2Ge0.8)S5I solid electrolytes, grown by vertical zone crystallization method (solution–melt technique), was studied using X-ray diffraction analysis by the Rietveld refinement method. The electrical conductivity of Ag7(Si1 − xGex)S5I solid solutions were measured by impedance spectroscopy technique in frequency range from 10 Hz to 2 × 106 Hz and temperature interval from 293 to 383 K. The compositional dependences of ionic part of total electrical conductivity and its activation energy were analyzed. The main features of the ion transport mechanism in Ag7(Si1 − xGex)S5I solid solutions caused by Si4+ ↔ Ge4+cationic substitution are explained via simple structural descriptors (SOF, dmax, ECoN). The spectral dependences of refractive index for Ag7(Si1 − xGex)S5I solid electrolytes were measured by the spectral ellipsometry technique. The spectrometric measurements of optical absorption edge in Ag7(Si1 − xGex)S5I solid solutions were carried out at room temperature. The compositional variation of energy pseudogap, Urbach energy and refractive indices in Ag7(Si1 − xGex)S5I solid solutions were studied.
