· In2Se

In₂Se is a layered III-VI semiconductor compound composed of indium and selenium, belonging to the family of van der Waals materials with a naturally layered crystal structure. Currently primarily investigated in research and development contexts, In₂Se shows promise for next-generation optoelectronic and electronic devices due to its tunable bandgap, ferroelectric properties, and strong light-matter interactions. Engineers consider In₂Se for applications requiring thin-film devices, nonlinear optical response, or integration into heterogeneous semiconductor stacks where its layered nature enables mechanical exfoliation or epitaxial growth.

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.
