As₄S₃ is an inorganic ceramic compound composed of arsenic and sulfur, belonging to the family of chalcogenide ceramics. This is a research-phase material studied for potential applications in optoelectronics and photonic devices, where its layered crystal structure and tunable bandgap properties are of interest. As a chalcogenide ceramic, it represents an alternative to traditional semiconductors for specialized infrared optics and nonlinear optical applications where conventional materials reach their performance limits.
