In1 Lu1 Au2

InLuAu₂ is an intermetallic compound combining indium, lutetium, and gold in a fixed stoichiometric ratio, classified as a semiconductor material. This is a research-phase compound with limited industrial deployment; intermetallics of this composition are primarily explored for specialized electronic and optoelectronic applications where the combination of rare earth (lutetium) and precious metal (gold) elements offers potential for unique band structure properties or contacts. The material belongs to an emerging class of ternary semiconductors studied for next-generation devices where conventional III-V or II-VI semiconductors reach fundamental limits, though practical applications remain largely in the development stage.
