Used in the production of gallium-based semiconductors such as gallium arsenide (GaAs) and gallium nitride (GaN), which are critical in high-frequency and high-power electronic devices. Applied in LED manufacturing for optoelectronic components, including blue and ultraviolet LEDs and laser diodes. Employed in photovoltaic cells for solar energy systems, especially in multi-junction solar cells with high efficiency. Utilized in research and development of liquid metal alloys and flexible electronics due to gallium’s low toxicity and unique fluid properties. Also used in some medical applications, such as targeted radiotherapy and imaging, when combined with specific isotopes.
