· Ag2 Bi2 P4 Se12

Ag₂Bi₂P₄Se₁₂ is a quaternary semiconductor compound combining silver, bismuth, phosphorus, and selenium into a layered crystal structure. This material belongs to the family of mixed-metal chalcogenophosphates, which are studied for their potential in thermoelectric conversion and photovoltaic applications due to their tunable bandgaps and anisotropic transport properties. While primarily in research and development rather than widespread commercial use, such compounds are investigated as candidates for mid-to-high temperature thermoelectric devices and emerging optoelectronic systems where conventional semiconductors face performance or cost limitations.
