· Cs2Sb

Cs₂Sb is a binary intermetallic compound composed of cesium and antimony, belonging to the semiconductor family of materials with potential applications in optoelectronic and photovoltaic systems. This material is primarily of research interest rather than established industrial production, studied for its electronic band structure and potential in photocathodes and photodetectors due to its light-responsive properties. Compared to more conventional semiconductors like silicon or III-V compounds, Cs₂Sb is notable for its low work function and sensitivity to visible and ultraviolet wavelengths, making it attractive for specialized vacuum electronics and quantum sensing applications where traditional semiconductors are unsuitable.

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.
