In4Cu2Te7

In4Cu2Te7 is a quaternary semiconductor compound belonging to the indium–copper–tellurium family, synthesized primarily for research into narrow-bandgap and thermoelectric materials. This material remains largely in the experimental phase, with potential applications in infrared detection, thermoelectric power generation, and specialized optoelectronic devices where its unique electronic structure could offer advantages over binary or ternary semiconductors; its development is driven by the search for efficient materials in thermal-to-electric energy conversion and mid-to-far infrared sensing.
