Thermoelectric (TE) materials are a kind of functional materials which can be used to convert directly heat energy to electricity or reversely. The thermoelectric effects hold great potential for application in power generation and refrigeration. Bi 2 Te 3 and its alloys are well known as best TE materials currently available near room temperature. This paper studies respectively the...
The effects of hot pressing on electric performance and mechanical strength of Bi 0.5 Sb 1.5 Te 3 thermoelectric material prepared through vacuum melting and milling were studied. The phase constituent and microstructure were analyzed by X-ray Diffraction and cold field emission Scanning Electric Microscope. Aeolotropisms of the material on microstructure and electric performances...
