Li2 Se4 In2

Li₂Se₄In₂ is a quaternary semiconductor compound combining lithium, selenium, and indium—a composition that places it in the family of mixed-metal chalcogenides with potential for optoelectronic and energy applications. This is primarily a research-phase material rather than an established industrial product; compounds in this family are investigated for photovoltaic absorbers, solid-state battery electrolytes, and infrared optics where the combination of light-element (Li, Se) and heavy-element (In) constituents can yield tunable bandgaps and ionic conductivity. Interest in such materials stems from their potential to overcome limitations of single-component semiconductors—particularly the ability to combine high carrier mobility with wide bandgap tunability and, in lithium-containing variants, enhanced ion transport for energy storage applications.
