· JVASP-100835· GaCuSe2

GaCuSe2 is a ternary chalcogenide compound combining gallium, copper, and selenium in a fixed stoichiometry. This is primarily a research and experimental material studied for its potential semiconducting and optoelectronic properties rather than an established industrial workhorse. The material belongs to the family of I-III-VI2 semiconductors, which are explored for photovoltaic devices, photodetectors, and nonlinear optical applications where conventional binary semiconductors have limitations.

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.
