· LiAsSe2

LiAsSe₂ is a ternary chalcogenide semiconductor compound combining lithium, arsenic, and selenium in a layered crystal structure. This material belongs to the family of mixed-valence semiconductors and is primarily of research interest rather than established in high-volume industrial production. Its potential applications center on infrared optics, solid-state batteries, and specialized photonic devices where its bandgap and optical transparency in the infrared region could provide advantages over more conventional semiconductors.
