Bi2 Te3热电材料的研究现状与发展趋势
Current studies and perspective of Bi2 Te3 thermoelectric materials
摘要
Abstract
At present, various thermoelectric materials have been developed and utilized. Due to the desirable thermoelectric material at room temperature, Bi2 Te3 has been a focus in the field of thermoelectric materials for decades. In this paper, the structure and properties of Bi2 Te3 materials are outlined by introducting briefly thermoelectric materials. The latest progress of Bi2Te3-based thermoelectric materials and the methods to improve their properties are reviewed.The main routes are adopted, one being the increase in the carrier mobility or the Seebeck coefficient to improve the power factor, and the other the increase in the phonon scattering at different wavelengths to reduce the lattice thermal conductivity. In addition, the prevailing topic of Bi2 Te3 based materials and the future development trend of Bi2 Te3 based thermoelectric materials are presented.关键词
