Zn1 Cu2 Ge1 S4
semiconductor· Zn1 Cu2 Ge1 S4
ZnCu₂GeS₄ is a quaternary semiconductor compound combining zinc, copper, germanium, and sulfur in a sulfide crystal structure. This material belongs to the family of I-III-IV-VI₄ semiconductors and is primarily of research interest for photovoltaic and optoelectronic applications due to its tunable bandgap and potential for high absorption coefficients. The material is notable as an alternative to traditional binary or ternary semiconductors, offering compositional flexibility for band engineering, though it remains largely in the development phase compared to established photovoltaic materials like CIGS or perovskites.
