· In2FeSe4

In2FeSe4 is a ternary semiconductor compound belonging to the chalcogenide family, combining indium, iron, and selenium in a layered or spinel-like crystal structure. This material remains primarily in the research phase, investigated for potential applications in thermoelectric devices, photovoltaic absorbers, and solid-state electronics where mixed-valence transition metals can enable tunable electronic properties. Unlike binary semiconductors, the three-element composition offers opportunities to engineer band gaps and carrier mobility through compositional control, though industrial adoption is limited and material synthesis and characterization are still active research areas.

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.
