In1 Bi1

InBi (indium bismuth) is a binary semiconductor compound that belongs to the III-V semiconductor family, though it represents a less common combination compared to mainstream III-V materials. This material is primarily of research interest for potential optoelectronic and thermoelectric applications, where its narrow bandgap and unique band structure could offer advantages in infrared detection, narrow-bandgap photovoltaics, or low-temperature thermoelectric generators. While not yet commercially dominant, InBi and related narrow-gap semiconductors are investigated as alternatives to mercury cadmium telluride (HgCdTe) and other toxic or difficult-to-process materials, particularly for infrared sensing in military and scientific instrumentation.
