Ge2 As4 Cd2
semiconductor· Ge2 As4 Cd2
Ge₂As₄Cd₂ is a compound semiconductor belonging to the chalcogenide family, combining group IV (germanium), group V (arsenic), and group II (cadmium) elements. This material is primarily of research interest for infrared optics and photonic applications, where its wide transparency window in the mid-to-far infrared spectrum makes it valuable for sensing and thermal imaging systems. The cadmium-containing composition offers potential advantages in nonlinear optical properties and tunable bandgap characteristics compared to simpler binary or ternary semiconductors, though it remains largely an experimental material in specialized optics rather than mainstream industrial production.

Quality & Standards
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.
