摘要：

The electronic properties of liquid Ag1-xSx have been measured as a function of temperature and concentration near the stoichiometric composition Ag2S. The unusual negative temperature dependence of the conductivity at stoichiometry found previously has been confirmed, and shown to extend over the composition range 0.3250<or=x<or=0.3345. The concentration dependence of the conductivity shows a sharp peak at the stoichiometric composition reaching a value of 250 Omega -1 cm -1 at 1000 degrees C; such a feature has never been observed in a liquid semiconductors with a comparable conductivity. The thermopower of liquid Ag1-xSx is negative and shows a broad minimum centred around the composition x=0.315.
