Answer: cannot emit light and has speed limitations

Step-by-step explanation:

Silicon is usually used in computer chips and solar cells but Gallium arsenide is regarded as a better alternative even though it's costly than silicon.

Gallium arsenide has technical advantages over silicon as its electrons

move through it faster than they move through silicon. Also, cannot emit light and has speed limitations.
