· IrSe2

IrSe₂ is a binary compound semiconductor composed of iridium and selenium, belonging to the transition metal dichalcogenide family. It is primarily of research and developmental interest for next-generation electronic and optoelectronic devices, valued for its layered crystal structure and potentially tunable band gap properties. Compared to more established dichalcogenides like MoS₂, IrSe₂ offers the possibility of higher carrier mobility and enhanced spin-orbit coupling due to iridium's heavy element character, making it a candidate material for advanced nanoelectronics, quantum devices, and potentially thermoelectric or catalytic applications.

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.
