Abstract

High-entropy materials (HEMs) hold promise for a variety of applications because their properties can be readily tailored by selecting specific elements and altering stoichiometry. In this Perspective, we highlight the emerging potential of HEMs in energy and electronic applications. We place particular emphasis on (ionic and covalent) ceramics that have only emerged in powder form since 2015. Although the discovery of opportunities is in its early stages, we discuss a few case studies in which the use of HEMs has led to improved material properties and device performance. We also correlate features with the respective properties and identify topics and effects for future investigations. An overview of these intrinsic properties, such as cocktail effects, lattice distortions and compositional freedom, as well as a list of general attributes, is given and linked to changes in material characteristics.
