Structure of two liquid semiconductors : Ag{sub 1-x}Se{sub x} and Ag{sub 0.67}Te{sub 0.33}.
Neutron diffraction measurements have been carried out on Ag{sub 1-x}Se{sub x} and Ag{sub 0.67}Te{sub 0.33} alloys to investigate possible structural causes for the differences in electrical transport properties observed in the two alloys. Ag{sub 1-x}Se{sub x} was measured for the compositions, x=0.30, 0.33 and 0.36, at temperatures just above the liquidus (1045, 915 and 855 degrees C, respectively), and for x=0.33 at three temperatures (915, 985 and 1045 degrees C). The Ag{sub 1-x}Te{sub x} system was measured at only one composition x=0.33, just above the liquidus (985 degrees C). At the level of the average correlation function, the behavior of liquid Ag-Se shows no unusual dependence on either concentration or temperature, and the selenium and tellurium alloys show generally similar behavior. There is no obvious structural connection with the anomalous concentration dependence of the electrical conductivity in Ag{sub 1-x}Se{sub x} alloys or with the different behavior in both electronic and ionic conduction observed in the Ag-Se and Ag-Te systems.
