Intrinsic & Extrinsic Semiconductors

In an intrinsic semiconductor, at any ordinary temperature, the correct relation between the number of electrons per unit volume ( $n_e$ ) and number of holes per unit volume ( $n_h$ ) is

Show answer and solution

Answer: (a)

In an intrinsic semiconductor every broken covalent bond gives one free electron and one hole.
So $n_e = n_h = n_i$ (non-zero at ordinary temperature).
So the answer is (a) $n_e = n_h$ .
