Y4 Se4 F4
semiconductor· Y4 Se4 F4
Y₄Se₄F₄ is an experimental mixed-anion semiconductor compound combining yttrium, selenium, and fluorine in a layered or framework structure. This material family (rare-earth chalcogenide fluorides) is primarily of research interest for its potential in optoelectronic and photonic applications, where the combination of anion types can tune bandgap and electronic properties compared to single-anion alternatives.
