Mechanism and Current Status of New Thermoelectric Materials
As a functional material that converts energy between different forms, thermoelectric materials have the great potential to be used in applications such as waste heat recycling, sensing, cooling and refrigeration, deep space exploration. Requirements for excellent thermoelectric materials include high Seebeck coefficient, low thermal conductivity and high electrical conductivity. With the development of the technology and the improvement of Environmental awareness, research for the thermoelectric materials with high Seebeck coefficient, high mechanical properties, reliability, workability and environmental-friendliness, has been of great importance. This article reviews the mechanism of thermoelectric effects, approaches of enhancing the thermoelectric properties and current status of thermoelectric materials, and then outlook the potential applications of thermoelectric materials.
