· K1 Li1 Zn1 S2

K1Li1Zn1S2 is an experimental quaternary sulfide semiconductor compound combining potassium, lithium, zinc, and sulfur. This mixed-cation sulfide belongs to the class of multinary semiconductors being investigated for optoelectronic and photovoltaic applications, where the combination of alkali metals and transition metals in a sulfide matrix offers tunable electronic properties and potential for wide bandgap engineering. Research into such compounds is driven by interest in alternative absorber materials and defect-tolerant semiconductors for next-generation solar cells, light-emitting devices, and radiation detection, though the material remains largely in exploratory stages with limited industrial deployment.

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.
