Effects of production conditions on the properties of Cu/sub 6/PS/sub 5/Hal crystals
Cu/sub 6/PS/sub 5/Hal single crystals belong to the class of compounds having the argyrodite structure; they have high disordered-vacancy concentrations, so they show high ionic conductivity even at room temperature. Various values have been quoted for the conductivities of Cu/sub 6/PS/sub 5/Hal, which may be due to differing growth conditions. The authors have examined the effects of those conditions on some electrophysical and optical parameters. The crystals were grown by chemical transport reaction. Differences in Cu/sub 6/PS/sub 5/Hal production conditions were found to affect the absorption edge and broaden the exciton-impurity absorption band, whose intensity alters, as well as increasing the Rayleigh flank intensity in the Raman spectrum on account of increased copper concentrations.
