· Nb2 Se4

Niobium diselenide (Nb₂Se₄) is a layered transition metal chalcogenide semiconductor belonging to the family of two-dimensional materials with anisotropic crystal structure. This compound is primarily investigated in materials research for next-generation electronics and energy applications, where its semiconducting properties and layer-dependent behavior make it attractive as an alternative to commercially established materials like MoS₂ for field-effect transistors, photodetectors, and catalytic devices.

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.
