K2ZnTe2 is a ternary semiconductor compound combining potassium, zinc, and tellurium in a 1:1:2 stoichiometry. This is a research-stage material belonging to the family of II-VI and multinary semiconductors, which are studied for optoelectronic and photovoltaic applications where tunable bandgap and lattice properties are advantageous. While not yet widely commercialized, compounds in this family are investigated for infrared detectors, solar cells, and wide-bandgap device applications where conventional semiconductors like CdTe or GaAs have limitations.
