Era of Entropy: Synthesis, Structure, Properties, and Applications of High-Entropy Materials

Interest in high-entropy materials continues its upward trajectory, with broad cross-discipline interest from physics, materials science, chemistry, and engineering. From compositionally complex to high-entropy alloys and ceramics, the breadth of customizability in structure-property relationships in these systems continues to diversify—leading to unexpected and exciting results in areas related to catalysis, ion transport, mechanical properties, phase stability, corrosion/oxidation resistance, hydrogen storage, magnetism, thermal transport, and radiation resistance. Highlighting the latest developments in this exciting new class of materials, this joint APL/JAP special topic is timely as it will provide a current snapshot on the various ongoing efforts related to understanding the effects of high compositional complexity in conventional structure-process-property-performance relationships. The collection further aims to provide perspectives in emerging areas of research including materials design, characterization, and functional properties of high-entropy alloys, ceramics, thin films, and single crystalline materials.
