· SeS

Selenium sulfide (SeS) is a binary semiconductor compound combining selenium and sulfur, belonging to the chalcogenide material family. It is primarily investigated in research and emerging applications for optoelectronic devices, photovoltaics, and infrared sensing systems where its narrow bandgap and optical properties offer potential advantages. The material remains largely in the experimental phase compared to more established semiconductors, but shows promise in specialized applications requiring combined thermal stability and semiconducting behavior in the chalcogenide class.

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.
