· Ta1 Cu3 Te4

Ta₁Cu₃Te₄ is a ternary semiconductor compound combining tantalum, copper, and tellurium elements, belonging to the family of complex metal tellurides with potential for thermoelectric or optoelectronic applications. This is an experimental/research material not yet widely deployed in production; it is studied primarily for its electronic band structure and potential use in energy conversion or sensing devices where the unique combination of these three elements offers tunable properties distinct from binary semiconductors.
