gallium arsenide chip

Gallium arsenide (GaAs) is a synthetic compound used as a semiconducting material in computing and communications. While silicon is the most common material for integrated circuits, GaAs offers advantages like higher electron mobility, leading to faster operating speeds and lower voltage operation. It is also more resistant to radiation, making it suitable for military and space applications.12

GaAs chips can run at higher speeds and consume less power than silicon chips, making them of interest for portable devices. However, GaAs is more brittle and costly to produce than silicon, limiting its widespread use. Despite these challenges, GaAs is employed in some high-frequency communication systems and has been used in supercomputers for its speed. A key advantage of III-V compounds like GaAs is their ability to be tailored to generate or detect photons of specific wavelengths, enabling them to perform both electronic and photonic functions within a single integrated circuit.32
