Volkmar Leute,H. Rusche +1 more
TL;DR: In this paper, the authors measured the electrical conductivity of α-phase Ag2HgI4 near the transformation temperature by X-ray diffraction and estimated the dependences of the entropy and of the Gibbs energy for migration of Ag-ions on temperature and on composition.

Effect of hydrostatic pressure on the electrical conductivity of Ag2HgI4 and Cu2HgI4
TL;DR: In this article, the electrical conductivity of the α and β phases of Ag2HgI4 and Cu2GI4 has been measured as a function of hydrostatic pressure up to 3 × 108 N m −2 in the temperature range between 283 and 363 K. The results are discussed on the basis of the continuum model for the atomic transport process.

Single crystal polarized Raman spectra of the solid electrolyte Cu2HgI4; attempt frequencies for ion motion in Ag2HgI4
TL;DR: In this article, the anomalous preexponential factor in the Arrhenius expression for ion hopping is discussed in light of the observed attempt frequency; they conclude that despite the high activation energy the conduction mechanism is similar to other heavy-metal solid electrolytes.
