· Pa4 S6

Pa4S6 is a phosphorus-arsenic sulfide compound belonging to the family of chalcogenide semiconductors, which are materials composed of elements from groups 15-16 of the periodic table bonded with sulfur or selenium. This material is primarily of research interest for advanced optoelectronic and photonic applications, where its tunable bandgap and sulfur-based composition offer potential advantages in infrared sensing, nonlinear optical devices, and specialized detector systems compared to more conventional semiconductors.
