K1 Li1 Zn1 S2
semiconductor· 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.
