· JVASP-35948· Sc2ZnSe4

Sc₂ZnSe₄ is a quaternary ceramic compound combining scandium, zinc, and selenium, belonging to the class of mixed-metal selenide ceramics. This is a research-phase material primarily of interest in optoelectronic and semiconductor applications, where its crystal structure and bandgap properties are being investigated for potential use in infrared optics, photovoltaic devices, or wide-bandgap semiconductor platforms. The material remains largely experimental; engineers would evaluate it only for advanced photonic or solid-state device development where its specific electronic or optical characteristics offer advantages over established alternatives like conventional II-VI semiconductors.
