摘要：

The study of the Bi-Sb-Te ternary phase diagram allowed us to identify a zone in the Te-rich side of the diagram where n-type materials can be obtained. The solid solutions of Bi-Sb-Te were synthesized by mechanical alloying with a 10:1 ball to powder weight ratio. Two solid solutions showing n-type conductivity were found. They exhibit very promising carrier concentration values for thermoelectric applications. (C) 1998 Elsevier Science Ltd. All rights reserved.
