· Ge1 Se4 Hg2

Ge1Se4Hg2 is a ternary chalcogenide semiconductor compound combining germanium, selenium, and mercury. This is a specialized research material rather than a commercialized engineering alloy, belonging to the broader family of chalcogenide glasses and semiconductors known for tunable optical and electrical properties. Chalcogenide semiconductors containing mercury are primarily explored in infrared photonics, nonlinear optical devices, and specialized sensing applications where their wide bandgap tunability and transparency in the mid-to-far infrared region offer advantages over conventional semiconductors; however, mercury content and material toxicity concerns limit widespread industrial adoption, making this compound most relevant to advanced research environments and high-performance optical system development.

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.
