| 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 this context, numerous studies have demonstrated the potential of sulfide materials for thermoelectric applications over the temperature range 300-700 K. Although most materials have high thermal conductivities, recent works demonstrated that extremely low thermal conductivities could be achieved in sulfides through order/disorder phenomena, rattling dynamics, and weak bonding of some crystal structures.
During this presentation, recent advances in sulphide compounds 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. |
