Used in semiconductor applications, particularly in the development of infrared detectors and optoelectronic devices. Its narrow bandgap makes it suitable for detecting long-wavelength infrared radiation. Also investigated for use in thermoelectric materials due to its ability to convert heat into electricity efficiently. Thin films of this compound are explored in chalcogenide-based phase-change memory devices and as a component in certain types of solar cells. Additionally, it serves as a precursor for synthesizing other indium and tellurium-containing compounds used in electronic and photonic technologies.
