· JVASP-103094· Ge2TeSe

Ge2TeSe is a ternary chalcogenide ceramic compound combining germanium, tellurium, and selenium. This material belongs to the family of amorphous or crystalline chalcogenide glasses and ceramics, which are primarily investigated for infrared optics and phase-change memory applications. The material is notable in research contexts for its potential in infrared-transparent windows, thermal imaging systems, and advanced memory devices, where its chalcogenide composition offers advantages in refractive index tuning and switching behavior compared to conventional oxides.
