Research focusing on the interplay between structural features and transport properties in inorganic materials is of paramount importance for the identification, comprehension and optimisation of functional materials. Researchers from CRISMAT laboratory and the Rennes Institute of Chemical Sciences (ISCR) have proposed a classification of inorganic copper sulphides based on their crystallographic features and the analysis of their transport properties. It provides guidelines to help estimating some properties of new materials by considering only their chemical composition and crystal structure. The classification relies essentially on Earth-abundant copper sulphides that have received considerable attention from scientists as the urgency remains to discover and improve the efficiency of sustainable materials for energy applications.
