Question

If $n_p$ and $n_e$ are the number of holes and conduction electrons in an intrinsic semiconductor then _________.

• A. $n_p>n_e$
• B. $n_p=n_e$
• C. $n_p<n_e$
• D. $n_p\ne n_e$

Answer 1

The correct option is B $n_p=n_e$

In an intrinsic semiconductor,

no. of holes=no.of electrons

So,

$n_p=n_e$
