In2FeSe4
semiconductor· 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.
