Cu-Bi-Te Cu-Bi-Te BASED THERMOELECTRIC MATERIALS AND METHOD OF FORMING THE SAME

摘要

A Cu-Bi-Te-based thermoelectric material and a method of forming the same are provided. A method of forming the Cu-Bi-Te-based thermoelectric material includes a step of reacting Cu, Bi, and Te to form Cu-Bi-Te-based powder, and a step of sintering the Cu-Bi-Te-based powder. The Cu-Bi-Te-based powder may be formed by solid-phase reaction between Cu and Bi-Te-based powder. The sintering may be performed by a spark plasma sintering (SPS) process. The Cu-Bi-Te-based thermoelectric material is formed by the above method. The Cu-Bi-Te-based thermoelectric material may be n type. It is possible to provide a Cu-Bi-Te-based thermoelectric material with excellent performance at room temperature.
