BaIn2Se4

BaIn₂Se₄ is a ternary semiconducting compound belonging to the chalcogenide family, combining barium, indium, and selenium in a layered crystal structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, particularly in the development of wide-bandgap semiconductors and infrared detectors where its layered electronic structure and optical response are potentially advantageous. While not yet widely deployed in production, BaIn₂Se₄ represents an emerging candidate in the broader class of metal selenide semiconductors being explored for next-generation devices requiring tunable band structure or enhanced performance in specific spectral regions.
