· K3Sm(AsS4)2

K3Sm(AsS4)2 is a rare-earth chalcogenide semiconductor compound combining potassium, samarium, arsenic, and sulfur in a layered crystal structure. This is a research-phase material studied primarily for its potential as a wide-bandgap semiconductor and photonic material, rather than an established industrial compound. The rare-earth and arsenic-sulfur framework places it in the family of functional inorganic semiconductors being explored for nonlinear optical effects, infrared applications, and exotic electronic properties that differ from conventional Si or III-V semiconductors.

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.
