Question

In an intrinsic semiconductor, if $N_e$ is the number of electrons in the conduction band and $N_p$ is the number of holes in the valence band then.

• A. $N_e>N_p$
• B. $N_e=N_p$
• C. $N_e<N_p$
• D. None of the above

Answer 1

The correct option is B $N_e=N_p$

In an intrinsic semiconductor, the number of electrons in the conduction band is equal to the number of holes in the valence band, so $N_e=N_p$.
