From order to disorder: Multicomponent layered carbides suggest tipping point for ‘high entropy’ classification

The term “high entropy” originally was applied to any material containing five or more elements in near-equimolar proportions, but some groups have called attention to the nuances that are missed with this generous usage. A multi-institution study led by Purdue University characterized layered carbides to clarify when the classification of multicomponent materials tips from “compositionally complex” to “high entropy.”
