Sr4 P4 Se12
semiconductor· Sr4 P4 Se12
Sr₄P₄Se₁₂ is a mixed-anion semiconductor compound combining strontium, phosphorus, and selenium in a tetrahedral framework structure. This is a research-phase material from the family of complex chalcogenide semiconductors, investigated primarily for its potential in photovoltaic energy conversion and solid-state optoelectronic devices due to its tunable bandgap and direct band-structure properties. Unlike conventional binary semiconductors (Si, GaAs), these multinary compounds offer flexibility in engineering electronic and optical properties for next-generation solar cells and light-emitting applications, though industrial deployment remains limited.
