  • Abstract
    Bi2Te3-Sb2Te3 alloys were prepared by the mechanical alloying method and sintered at the temperatures ranging from 50 to 550°C to ensure the phase equilibrium at low temperatures. A micro-phase diagram near the stoichiometric composition was evaluated with the carrier concentration which was estimated from the values of the Seebeck coefficient. Singular properties of the Seebeck coefficient and the electrical resistivity observed at the composition of 20% Bi2Te3-80% Sb 2Te3 were also discussed
