· K2 Li4 As2

K2Li4As2 is an experimental quaternary semiconductor compound combining potassium, lithium, and arsenic elements. This material belongs to the family of mixed-cation arsenide semiconductors, which are primarily investigated in research settings for potential optoelectronic and photovoltaic applications. While not yet commercialized in mainstream engineering, compounds in this chemical family are of interest for their tunable band structure and potential use in next-generation solar cells or light-emitting devices, though synthesis challenges and stability issues currently limit practical deployment.
