The current due to electron flow in conduction band is the hole current in valence band?
Correct answer: C. greater than
- A. equal to
- B. less than
- C. greater than
- D. any of the above
Explanation
For the same electric field in an intrinsic semiconductor, electron and hole concentrations are equal, but electron mobility is higher than hole mobility. Hence the electron current in the conduction band is greater than the hole current in the valence band.
