Ba4Ge3Se9Cl2
semiconductor· Ba4Ge3Se9Cl2
Ba4Ge3Se9Cl2 is a mixed halide-chalcogenide semiconductor compound combining barium, germanium, selenium, and chlorine in a layered crystalline structure. This is a research-phase material studied primarily for infrared (IR) optical and nonlinear optical applications, where the combination of selenide and chloride ligands offers tunable bandgap and enhanced transparency in the mid-to-far IR region compared to single-anion chalcogenides. The material belongs to an emerging class of functional semiconductors designed for photonics and optoelectronics rather than conventional semiconductor electronics.
