Used in semiconductor applications due to its electronic properties, particularly in the development of infrared optics and optoelectronic devices. It serves as a precursor material for synthesizing advanced chalcogenide glasses that are transparent in the infrared range, making it valuable for thermal imaging systems, infrared lenses, and fiber optics. Also investigated for use in thin-film solar cells and as a component in certain types of transistors and sensors. Its ability to form stable amorphous films supports its integration into memory devices and phase-change materials.
