Ba2 B4 Se12

Ba₂B₄Se₁₂ is a ternary chalcogenide semiconductor compound combining barium, boron, and selenium—a research-phase material that belongs to the family of metal boron chalcogenides with potential for infrared and optoelectronic applications. This material class is of interest in the semiconductor research community for mid- to long-wavelength infrared detection and nonlinear optical devices due to the wide bandgap and favorable optical transparency window of selenium-based compounds. While not yet mature for mainstream industrial production, Ba₂B₄Se₁₂ represents an exploratory composition in the borochalcogenide family, primarily studied in academic and specialized photonics research environments for applications where conventional III–V or II–VI semiconductors fall short.
