· Sc4 I4 O4

Sc₄I₄O₄ is an experimental mixed-anion semiconductor compound containing scandium, iodine, and oxygen. This material belongs to an emerging class of hybrid halide-oxide semiconductors being investigated for optoelectronic and photovoltaic applications where conventional semiconductors face limitations. Research into such compounds focuses on tunable bandgaps, potential high carrier mobility, and the ability to engineer electronic properties through anion mixing—making them candidates for next-generation solar cells, light-emitting devices, and radiation detectors, though practical device integration remains largely in the laboratory phase.

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.
