· Sc1 Ge1 Au1

ScGeAu is an intermetallic compound combining scandium, germanium, and gold in a 1:1:1 stoichiometry. This is a research-stage material rather than an established commercial semiconductor; it belongs to the class of ternary intermetallics being investigated for potential optoelectronic and quantum applications where the combination of rare-earth (Sc), group IV (Ge), and noble metal (Au) elements may offer unique electronic band structures or phononic properties.

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.
