· K4 In2 P4 S14

K₄In₂P₄S₁₄ is a quaternary semiconductor compound composed of potassium, indium, phosphorus, and sulfur, belonging to the family of mixed-anion semiconductors with complex crystal structures. This material is primarily of research and developmental interest rather than established commercial production, investigated for its potential in optoelectronic and photovoltaic applications due to its tunable bandgap and layered structural properties. The compound represents an emerging class of semiconductors designed to explore alternatives to conventional binary and ternary semiconductors, with particular focus on applications requiring specific optical or electronic characteristics not easily achieved in simpler material systems.
