In what application is gallium arsenide used as a semiconductor material?
Pick an answer to check it.
Answer: C. In microwave circuits
Gallium arsenide lets electrons move faster than in silicon, so GaAs devices work well at microwave frequencies. It is not chosen for high-current rectifiers or audio.
Tip: GaAs = GHz.
