Electrical and thermal properties of rectangular quantum wires of polycrystalline bismuth telluride have been investigated in the framework of the relaxation time approximation. Electrical conductivity, electronic thermal conductivity and thermopower have been obtained in the temperature range 200-6
Pure and Bi-doped samples of SrTiO: with Sr/Ti ratios ranging from 0.980 to 1.010 were sintered in air at 1500 ยฐC. Grain growth was promoted in the non-stoichiometric bismuth-doped compositions. Unlike the non-doped samples which were ohmic insulators, bismuth-containing specimens showed non-ohmic b
