Аннотация:We present some results on physical and electrical properties of the Skutterudites CoSb/sub 3/ and mixed alloys. Most of samples measured were polycrystalline, which have been prepared by hot-pressing of powders under 10/sup 7/ Pa at /spl sim/650/spl deg/C and /spl sim/750/spl deg/C, and a few measurements on CoSb/sub 3/ single crystals were performed. We report some results of the Hall mobility, Seebeck coefficient and electrical conductivity measurements on CoSb/sub 3/ and mixed alloys. Based on the experimental results, we make clear important factors which have influence on the electronic transport properties, in particular, on the Hall mobility of the materials.
