· Sn1 Se2

Tin diselenide (SnSe₂) is a layered semiconductor compound belonging to the transition metal dichalcogenide family, characterized by a structure consisting of stacked two-dimensional sheets held together by van der Waals forces. While primarily studied in research contexts for next-generation electronics and optoelectronics, SnSe₂ is being investigated for applications requiring tunable bandgap, high electron mobility, and strong light-matter interactions—particularly in thin-film photovoltaics, field-effect transistors, and photodetectors where its layered structure enables novel device engineering not possible with conventional semiconductors.

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.
