Topic: Electronic Devices
Compared to Silicon, GaAs Semi-conductors offer advantage of
- A. Higher Electron Mobility
- B. Higher frequency operation
- C. Lower leakage current
- D. All of the above
Answer: D. All of the above
Explanation: Gallium Arsenide (GaAs) has significantly higher electron mobility compared to Silicon, allowing for faster and higher frequency operation. Additionally, GaAs has a wider bandgap than Silicon, which results in lower intrinsic carrier concentration and therefore lower leakage current, especially at high temperatures.
