Topic: Electronic Devices
Measurement of Hall coefficient enables the determination of
- A. Temperature coefficient and thermal conductivity
- B. Mobility and concentration of charge carriers
- C. Fermi level and forbidden energy gap
- D. None of the above
Answer: B. Mobility and concentration of charge carriers
Explanation: Hall experiment is used to determine whether a semiconductor is n-type or p-type and the carrier concentration. Also by simultaneously measuring the conductivity $\sigma$, the mobility $\mu$ can be calculated.
