· ReSe2

ReSe₂ is a layered transition metal dichalcogenide (TMD) semiconductor composed of rhenium and selenium atoms arranged in a stacked structure. This material is primarily of research interest for next-generation electronics and optoelectronics, where its layer-dependent properties enable applications in 2D device engineering, field-effect transistors, and photodetectors as an alternative to more established TMDs like MoS₂. The relatively weak interlayer bonding makes it amenable to mechanical exfoliation into ultrathin films, positioning it as a candidate material for flexible electronics and van der Waals heterostructure engineering.

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.
