Thermoelectrics (TE) are green materials that can contribute to environmental sustainability via harvesting of waste heat and converting it into electricity. IMRE has developed a complete synthesis and characterization protocol for thermoelectric materials. Material systems that have been studied include organic polymers, organic-inorganic hybrid materials, and 2D materials. A comprehensive suite of characterization tools has been developed, including tools for thermal conductivity measurements and electrical characterization at cryogenic temperatures.
A typical thermoelectric material should have high electrical conductivity coupled with low thermal conductivity so as to maintain a temperature gradient. IMRE has built up a series of equipment and system to help to characterize the thermoelectric properties of the new TE material, which include bulk and thin-film materials.
- Thermoelectric characterization system (Bulk and thin film)
- ZEM3-HR system (Seebeck and electrical conductivity)
- NanoTR system (Thermal Diffusivity and Thermal Effusivity)
- Heat capacity
- Thermal conductivity
