Electronic Properties of Liquid Se–Te Mixtures Containing Noble Metal Solutes

抄録

The increase in the conductivity, Δσ, and the increase in the paramagnetic susceptibility, Δχ_p, by the addition of noble metal solutes were experimentally studied in liquid Se–Te mixtures. The curve of Δσ versus the square root of the conductivity of solvent σ^1⁄2 has a broad maximum in the intermediate region where metal-nonmetal transitions gradually occur in liquid Se–Te mixtures. The trend of Δχ_p versus σ^1⁄2 has also a broad maximum in the relatively low conductivity region. The broad maxima of Δσ and Δχ_p are suggested to be closely related to the formation of the delocalized threefold site and the dangling bond state which are induced by the addition of noble metal solutes.
