| Abstract Scope |
Thermoelectricity offers a promising solution to address energy scarcity by enabling the efficient conversion of waste heat into useful electricity. Continued research and development in this field can lead to the development of more efficient and cost-effective thermoelectric materials, which can play a significant role in addressing the global energy challenge.
In particular, the understanding of the crystal chemistry and transport properties relationships is fundamental to design more efficient materials.
During this presentation, recent advances in sulfides, chalcohalides and halides will be discussed. Some peculiar structural features in connection with materials synthesis, chemical bonds, lattice vibrations, structure dimensionality were carefully examined to establish rules and correlations between the crystal structures, nano-microstructures, electronic structures, vibrational and thermoelectric properties. |
