· YAs

Yttrium arsenide (YAs) is a binary compound semiconductor ceramic combining yttrium and arsenic, belonging to the III-V semiconductor material family. It is primarily investigated in research and specialized optoelectronic applications where direct bandgap semiconductors are needed for light emission and detection in the infrared spectrum. YAs offers potential advantages in high-frequency and high-power device development, though it remains less commercialized than mainstream semiconductors like GaAs; its utility depends on specific wavelength requirements and integration with existing device architectures.

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.
