Ge2 Se8 Sr4
semiconductor· Ge2 Se8 Sr4
Ge₂Se₈Sr₄ is a chalcogenide semiconductor compound combining germanium, selenium, and strontium elements. This is a research-phase material within the chalcogenide glass and crystal family, investigated for its potential in infrared optics, phase-change memory devices, and photonic applications where selenium-based semiconductors offer transparent windows in the infrared spectrum. The strontium incorporation modifies the material's thermal stability and electronic properties compared to binary Ge-Se systems, making it of interest to researchers exploring novel compositions for next-generation optoelectronic and memory technologies, though industrial production and deployment remain limited.
