Perspectives are offered in designing future high-performance functional materials utilizing the high-entropy concepts and high-throughput predictive computational modeling. Extending the concept of high configurational entropy to a wide range of materials such as intermetallics, ceramics, and semiconductors through the isostructural design approach is discussed. Comparisons of functional properties between HEAs and conventional low- and medium-entropy materials are provided, and examples are illustrated using computational modeling and tuning the composition of existing functional materials through substitutional or interstitial mixing. The objective of this paper is to provide a brief, timely review on select functional properties of HEAs, including soft magnetic, magnetocaloric, physical, thermoelectric, superconducting, and hydrogen storage. All submissions will be subject to the same review process and editorial standards as regular Communications Materials Articles.While most papers on high-entropy alloys (HEAs) focus on the microstructure and mechanical properties for structural materials applications, there has been growing interest in developing high-entropy functional materials. We welcome the submission of any paper related to high-entropy alloys and ceramics. Synergy between high-entropy alloys and high-entropy ceramics.Advanced theoretical, simulation and experimental approaches.Property characterization, including for specific applications.Fundamental understanding of formation, structure and behavior.Topics of interest include the following: A secondary aim is to encourage an exchange of ideas between the high-entropy alloys and high-entropy ceramics communities. This Collection will bring together the latest thinking and new understanding of high-entropy alloys and ceramics, and works related to their applications. Interest in these materials is driven by: 1) advanced properties, which make them promising for applications such as structural components and in energy storage, and 2) fascinating science in how their properties are determined by their electronic, atomic and micro-scale structure. This has been demonstrated for a range of alloys and ceramics, which are generally known as ‘high-entropy’ materials. However, a new approach has emerged mixing similar amounts of each component can result in only a single- or few-phase material. The traditional approach to materials design is to start with a base composition and then tune its chemistry by adding smaller amounts of other elements or compounds.
