· JVASP-29582· CdHgAsBr

CdHgAsBr is a quaternary semiconductor ceramic compound combining cadmium, mercury, arsenic, and bromine elements. This material belongs to the family of II-VI semiconductors and represents a research-stage compound of primary interest in optoelectronic and infrared detector applications where tunable bandgap properties are valued. The combination of heavy elements affords potential use in radiation detection and specialized photonic devices, though commercial adoption remains limited compared to more established binary or ternary semiconductors.

Regulatory Screening

Environmental

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.
