High-Entropy Materials (HEM)

The High Entropy Materials Group focuses on the fundamental understanding of the high entropy concept as well as on correlating material structure and composition to its properties for a wide range of applications.

Group Photo HEM — High-Entropy Materials Group

The High-Entropy Materials group works on the comprehensive understanding of the high-entropy concept and on the utilization of high entropy materials (HEM) for different applications. Due to the versatility of HEM regarding composition and the connected structure/property relationships, a multitude of different areas of applications is conceivable.

Besides general investigations about the high-entropy concept itself and how to predict propterties in HEM, more application oriented topics are in our focus of interest and presented more in detail on the respective topic pages below. They include applications in electronic devices and energy storage, catalysis, band structure tailoring, and mangetism, as well as method development of high-throughput synthesis and analysis.
