In an intrinsic semiconductor relation between number of free electrons (ne) in conduction band and holes (nh) in valence band is given by: Correct Answer n<sub style="">e</sub> = n<sub style="">h</sub>

Explanation:

  • In an intrinsic semiconductor, the number of free electrons in the conduction band is equal to the number of holes in the valence band. The current caused by electrons and holes is equal in magnitude.

  • The total current in intrinsic semiconductor is the sum of hole and electron current.

Total current = Electron current + Hole current

I = Ihole+ Ielectron

So, In an intrinsic semiconductor relation between the number of free electrons (ne) in the conduction band and holes (nh) in the valence band is equal.

ne = nh
