· LiGaSe2

LiGaSe2 is a ternary semiconductor compound combining lithium, gallium, and selenium, belonging to the family of III–VI semiconductors with potential for optoelectronic and nonlinear optical applications. This material remains primarily in research and development phases, explored for its wide bandgap characteristics and crystal structure properties that could enable ultraviolet-to-infrared photonic devices, particularly in the mid-infrared spectral region where conventional semiconductors have limitations. Engineers and researchers investigate LiGaSe2 as a candidate for frequency conversion, laser generation, and advanced optical sensing systems where its nonlinear optical properties and transparency windows offer advantages over more established alternatives like GaAs or InP.

Export Control

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.
