· KInGeS4

KInGeS₄ is a quaternary semiconductor compound composed of potassium, indium, germanium, and sulfur, belonging to the family of ternary and quaternary chalcogenides. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its direct bandgap and layered crystal structure offer potential advantages in light emission, detection, and energy conversion; it represents an emerging class of wide-gap semiconductors being explored as alternatives to conventional III-V and II-VI compounds for specialized photonic and thermoelectric devices.

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.
