· Na0.5Ge1Pb1.75Se4

Na0.5Ge1Pb1.75Se4 is a mixed-cation chalcogenide semiconductor compound combining sodium, germanium, lead, and selenium—a composition designed to engineer the band gap and phonon properties for thermoelectric and infrared photonic applications. This is primarily a research-phase material rather than an established commercial product; compounds in this family are investigated for mid-infrared sensing, solid-state cooling via the Seebeck effect, and narrow-bandgap optoelectronic devices where the layered or distorted crystal structure can suppress lattice thermal conductivity while maintaining electronic transport.

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.
