· Ge1 Sb1

Ge1Sb1 is a binary semiconductor compound in the germanium-antimony system, representing a stoichiometric intermetallic or solid-solution phase. This material is primarily of research interest in phase-change memory (PCM) applications and semiconductor device engineering, where it exhibits potential for reversible thermal and electrical switching behavior. GeSb compounds are notable alternatives to widely-used Ge2Sb2Te5 formulations, offering potential advantages in switching speed, thermal stability, or crystallization kinetics depending on specific composition and processing conditions.

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.
