Atomic Cartography of High-Entropy Cs₂BCl₆ Perovskite-Inspired Materials: The Vital Role of Solid-State NMR Spectroscopy in Identifying Elemental Disorder.

ABSTRACT: The burgeoning field of high-entropy materials (HEMs) has sparked significant interest by leveraging synergistic "cocktail effects" from inexpensive and abundant elements to access unprecedented physical, optical, and chemical properties. While standard characterization techniques, such as diffraction and energy-dispersive X-ray spectroscopy, provide valuable insights, they often fall short in elucidating the intricate atomic-level disorder and the presence of nanoscale phase separation or persistent nanodomains. To overcome these limitations, this work introduces a robust and rapid analytical method based on solid-state ¹³³Cs nuclear magnetic resonance (NMR) spectroscopy, capable of directly probing atomic-level mixing in these complex materials. This technique is demonstrated
