· BaGa2SiSe6

BaGa₂SiSe₆ is a quaternary semiconductor compound belonging to the chalcogenide family, combining barium, gallium, silicon, and selenium into a crystalline structure. This is a research-stage material of interest in nonlinear optics and mid-infrared photonics applications, where its wide bandgap and potential for second-harmonic generation or parametric amplification could offer advantages over more common alternatives like GaAs or ZnSe in specific wavelength windows. The material represents exploration into mixed-metal chalcogenide systems for expanding the optical and electronic property space available to device designers working in infrared and quantum optics.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
