· Se1 Sn1

Se1Sn1 is a binary semiconductor compound composed of selenium and tin in a 1:1 atomic ratio, belonging to the IV-VI semiconductor family. This material is primarily of research interest for optoelectronic and thermoelectric applications, where tin-selenium compounds show potential as alternatives to conventional semiconductors due to their tunable bandgap and layered crystal structures. While not yet widely commercialized compared to established semiconductors, Se1Sn1 and related tin-selenium phases are investigated for thin-film photovoltaics, infrared detectors, and thermoelectric energy conversion where the combination of moderate mechanical stiffness and semiconductor properties may offer advantages in flexible or thermal-energy-harvesting device designs.

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.
