Materials science has been driven by the creation of novel materials and their applications. Among promising candidates, high-entropy materials (HEMs) have attracted significant attention due to their unique properties arising from their multi-principal-element compositions. In particular, HEMs are expected to serve as low-thermal-conductivity materials. In this study, dense high-entropy amorphous thin films, free from the influence of porosity, were fabricated using a combinatorial sputtering method and their thermal transport properties were investigated. As a result, HEM amorphous thin films exhibiting thermal conductivities significantly lower than those of conventional alloys were successfully identified.
