· JVASP-4020· DySBr

DySBr is a rare-earth chalcohalide ceramic compound combining dysprosium, sulfur, and bromine. This material belongs to an emerging class of layered ceramic compounds with potential applications in solid-state devices and thermal management systems. Currently primarily of research interest, DySBr and related rare-earth chalcohalides are being investigated for their unique electronic and phononic properties, positioning them as candidate materials for next-generation semiconducting ceramics, thermoelectric applications, and potentially as solid electrolytes or optical components.
