Sintered BI2TE3-based thermoelectric materials preventing P- to N- type transition

摘要

There are sintered Bi.sub.2 Te.sub.3 -based thermoelectric materials containing Ag.sub.2 S, which prevent p- to n-type transition of Bi.sub.2 Te.sub.3 -based thermoelectric materials during polycrystalline sintering and have improved thermoelectric properties.
