The effectiveness of a material for thermoelectric applications is determined by the dimensionless figure of merit, ZT= (S2)T/, where S is the Seebeck coefficient, is the electrical conductivity, is the thermal conductivity, and T is the absolute temperature. Therefore, in order to obtain high performance thermoelectric materials, the large S and the high as well as the low are required. In order to improve the efficiency of TE, we focus attention on the Au-Tl-Te ternary compounds and Bi-Te binary compounds as new class of thermoelectric materials , because they would be considered to exhibit low . We prepared the

materials by using the solid state reaction method. The obtained ingots were crushed into fine powders, followed by hot pressing. The crystal structure was analyzed by XRD. The thermoelectric properties were measured at temperatures ranging from room temperature to melting point temperature. The room temperature value is extremely low. So, the efficiency of TE will be improved.
