· Al4 S8 Zn2

Al₄S₈Zn₂ is a quaternary semiconductor compound combining aluminum, sulfur, and zinc elements, representing an emerging material in the chalcogenide semiconductor family. This composition belongs to the broader class of mixed-metal sulfides being investigated for optoelectronic and photovoltaic applications, where the multi-component structure may offer tunable bandgap and enhanced light absorption compared to binary sulfide semiconductors. As a research-stage material, Al₄S₈Zn₂ is notable for its potential in thin-film solar cells, photodetectors, and other solid-state devices where cost-effective, earth-abundant alternatives to traditional semiconductors are sought.

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.
