· LiAsS2

LiAsS₂ is a ternary lithium-arsenic sulfide semiconductor compound belonging to the chalcogenide family. This is primarily a research and developmental material studied for its semiconducting and potentially ionic-conducting properties, rather than an established industrial material. Its relevance lies in exploratory applications within solid-state electronics and energy storage research, where lithium-containing chalcogenides are investigated as alternatives to conventional semiconductors and as potential solid electrolyte candidates for advanced battery systems.
