· K2 Li2 Se2

K₂Li₂Se₂ is an experimental ionic semiconductor compound combining potassium, lithium, and selenium elements. This material belongs to the family of mixed-alkali metal chalcogenides, which are primarily of research interest for next-generation optoelectronic and solid-state energy storage applications. While not yet commercialized at scale, compounds in this class are investigated for their potential in thin-film photovoltaics, ion-conducting electrolytes, and infrared optical devices due to the tunable electronic properties enabled by multi-element ionic frameworks.
