· JVASP-35946· Sc2ZnS4

Sc₂ZnS₄ is a ternary ceramic compound combining scandium, zinc, and sulfur, belonging to the family of sulfide ceramics. This material remains primarily in the research and development phase, with potential applications in optoelectronics, photovoltaics, and solid-state devices where its unique crystal structure and electronic properties may offer advantages over conventional binary sulfide ceramics. Research into scandium-containing sulfides is motivated by the possibility of tuning bandgap energy and improving optical/electrical performance for specialized semiconductor applications.
