Thermoelectric Materials

Thermoelectricity refers to a class of phenomena in which a temperature difference creates an electric potential or an electric potential creates a temperature difference. 

Various metals and semiconductors are generally employed in these applications. NETZSCH offers comprehensive tools for material optimization and characterization in this area. To optimize thermoelectric devices, thermal properties must be known. The Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity has a direct impact on the efficiency of a thermoelectric material.
