· K2 In2 Te4

K₂In₂Te₄ is a ternary semiconductor compound belonging to the class of chalcogenide materials, combining potassium, indium, and tellurium. This is a research-stage material studied for its semiconductor properties and potential in optoelectronic and thermoelectric applications, rather than a material in widespread industrial production. Interest in this compound stems from the broader family of layered chalcogenides, which offer tunable band gaps and promising transport properties for next-generation energy conversion and light-emitting devices.
