Used in semiconductor applications, particularly in the development of optoelectronic devices and infrared detectors. It serves as a precursor for synthesizing gallium-based chalcogenide materials, which are important in solid-state electronics and photovoltaics. Its layered crystal structure also makes it suitable for research in two-dimensional materials and nanotechnology. Additionally, it finds use in specialized light-emitting diodes (LEDs) and laser technologies operating in the infrared range.
