Abstract Scope |
Among the various possibilities offered by the periodic table, copper-rich ternary and quaternary sulphides represent a formidable source for the discovery of low cost and environmentally benign thermoelectric materials. Copper-rich sulphides form an important class where univalent copper is the dominant element with the potential to generate hole carriers within the conductive “Cu–S” network for the generation of p-type thermoelectrics. Those materials represent a fantastic playground for solid state chemists. Some peculiar structural features in connection with chemical bonding, such as the existence of metal complexes within the structure and/or structural order/disorder phenomena, were carefully examined in different materials to establish rules and correlations between the crystal structures, electronic structures, vibrational and thermoelectric properties. |
