· Ge1 Se1

Ge₁Se₁ (germanium monoselenide) is a binary IV-VI semiconductor compound combining germanium and selenium in a 1:1 stoichiometric ratio. This material belongs to the chalcogenide semiconductor family and is primarily of research and development interest rather than established in high-volume commercial production. Ge₁Se₁ is investigated for optoelectronic and photonic applications due to its narrow bandgap and strong light-matter interactions, with potential uses in infrared detectors, thermal imaging systems, and phase-change memory devices; it offers advantages over traditional semiconductors in specific wavelength ranges and represents a platform for exploring tunable optical properties through composition and structural 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.
