BaTeSe (barium tellurium selenide) is a mixed-anion ceramic compound combining barium with tellurium and selenium, belonging to the chalcogenide ceramic family. This material is primarily of research interest for optoelectronic and infrared applications, where its semiconductor properties and wide bandgap characteristics make it relevant for thermal imaging systems, infrared detectors, and potentially for photovoltaic devices operating in specialized spectral ranges. BaTeSe represents an understudied composition within the chalcogenide material space and is not widely commercialized; its development is driven by the semiconductor and photonics research communities seeking alternatives to more established compounds like CdTe or lead chalcogenides for niche sensing and detection applications.
