· Si1 Ca3 Br2

Si₁Ca₃Br₂ is an experimental semiconductor compound combining silicon, calcium, and bromine, representing a mixed-halide perovskite-related material under investigation for optoelectronic and photonic applications. This composition falls within the broader family of halide semiconductors being explored in photovoltaics, photodetectors, and light-emission research, where the incorporation of alkaline-earth elements (calcium) alongside silicon and halogens aims to tune bandgap, stability, and charge-transport properties. The material remains largely at the research phase; its potential advantage over conventional semiconductors lies in solution-processability, tunable optical properties, and the possibility of lower-cost fabrication pathways compared to traditional silicon-based electronics.

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.
