GaAs (Gallium Arsenide)

Gallium Arsenide (GaAs) is a compound made of two elements, gallium and arsenic. It's a semiconductor, meaning it can conduct electricity under certain conditions. GaAs is widely used in electronics and optoelectronics, such as in solar cells, LED lights, and microwave devices. Its advantages include higher efficiency and faster operation than silicon, which is more commonly used. GaAs also performs better in high-frequency applications, making it valuable for things like mobile phone technology and satellite communications. Overall, GaAs plays a crucial role in modern electronics and communication technologies.
