· JVASP-3321· ZnGa2Te4

ZnGa₂Te₄ is a ternary II-VI semiconductor ceramic compound belonging to the defect tetrahedral structure family, combining zinc, gallium, and tellurium. It is primarily of research and developmental interest for optoelectronic and photovoltaic applications where wide bandgap semiconductors are needed, particularly in contexts where gallium telluride compounds offer advantages in radiation hardness or thermal stability compared to binary alternatives. The material is notable for potential use in space-grade solar cells, X-ray detection, and high-temperature semiconductor devices where its mixed-cation composition may provide tunable electronic properties unavailable in simpler binary compounds.
