· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
