· Li4 Ga4 Se8

Li₄Ga₄Se₈ is a quaternary semiconductor compound composed of lithium, gallium, and selenium, belonging to the family of lithium-based chalcogenide semiconductors. This is primarily a research-phase material investigated for its potential in optoelectronic and solid-state applications, particularly in infrared photonics and as a wide-bandgap semiconductor material where its layered crystal structure offers tunable electronic properties. The material family is notable for combining ionic (Li) and covalent (Ga-Se) bonding, making it attractive for applications requiring both semiconducting behavior and favorable transport properties, though industrial adoption remains limited compared to conventional gallium compounds.

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.
