· ErSe2

ErSe₂ is a rare-earth selenide semiconductor compound composed of erbium and selenium, belonging to the family of binary rare-earth chalcogenides. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in infrared optics, thermoelectric devices, and specialized electronic components where rare-earth semiconductors offer unique optical or thermal properties.

Export Control

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.
