semiconductor

· Ba4 I8

Ba₄I₈ is an inorganic halide semiconductor compound composed of barium and iodine in a 1:2 ionic ratio. This material belongs to the family of metal halide semiconductors, which are primary subjects of research for next-generation optoelectronic and photovoltaic applications. Ba₄I₈ is largely investigated in laboratory settings rather than established in mature industrial production, with potential applications in solid-state radiation detection, thin-film photovoltaics, and LED technologies where its electronic band structure and light-absorption properties may offer advantages over conventional semiconductors.

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.
