· Li2 In2 Se4

Li₂In₂Se₄ is a quaternary semiconductor compound belonging to the family of lithium indium selenides, which are characterized by layered crystal structures and wide bandgaps. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its semiconducting properties and potential for tunable electronic characteristics make it a candidate for next-generation thin-film devices and solid-state energy conversion systems. As an emerging compound rather than a commercial standard, Li₂In₂Se₄ is being investigated in academic and laboratory settings for applications where conventional semiconductors (such as Si or CdTe) may not meet requirements for specific wavelength ranges, thermal stability, or integration with other functional materials.
