Ga2Se3
semiconductor· Ga2Se3
Gallium selenide (Ga₂Se₃) is a III-VI semiconductor compound belonging to the gallium chalcogenide family, characterized by a layered crystal structure similar to other gallium selenides. While primarily a research material rather than a commodity semiconductor, Ga₂Se₃ is investigated for optoelectronic and photonic applications due to its direct bandgap and strong light-matter interaction, with potential advantages in mid-infrared detection, nonlinear optical devices, and thin-film photovoltaics where traditional semiconductors face 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.
