· AsS

Arsenic sulfide (AsS) is an inorganic semiconductor compound belonging to the chalcogenide family, characterized by arsenic and sulfur bonding in a network structure. It appears primarily in research and specialized optoelectronic applications rather than high-volume industrial use, with potential interest in infrared optics, photovoltaic research, and phase-change memory devices where its narrow bandgap and light-sensitive properties offer advantages over conventional semiconductors.
