· K2Hg3Se1.31S2.69

K2Hg3Se1.31S2.69 is a mixed chalcogenide semiconductor compound combining potassium, mercury, selenium, and sulfur in a layered crystal structure. This is a research-phase material studied for its tunable band gap and anisotropic electronic properties, typical of heavy-metal chalcogenide systems; it represents the broader family of metal chalcogenides being explored for next-generation optoelectronic and thermoelectric devices. While not yet commercialized, compounds in this chemical family are of interest where traditional semiconductors are limited by bandgap, charge carrier mobility, or radiation tolerance requirements.

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.
