· TaGaSe2

TaGaSe₂ is a ternary layered semiconductor compound combining tantalum, gallium, and selenium in a fixed stoichiometric ratio. This material belongs to the family of transition metal dichalcogenides and layered van der Waals semiconductors, currently investigated in research contexts rather than established high-volume production. Interest in TaGaSe₂ centers on its potential for optoelectronic and electronic device applications, where its layered crystal structure and tunable bandgap could enable novel photovoltaic, photodetector, and field-effect transistor designs—offering alternatives to more common 2D materials like MoS₂ when specific bandgap or carrier transport properties are required.

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.
