Question

In p-type semiconductor, ______.

Options

• n_h = n_e

• n_h < n_e

• n_h > n_e

• n_h >> n_e

Answer 1

In p-type semiconductor, n_h >> n_e.

Explanation:

In a p-type semiconductor, the number density of valence band holes (n_h) is roughly equal to the number density of acceptor atoms (N_a) and is quite large when compared to the number density of conduction band electrons (n_e).

As a result, n_h ≈ N_a >> n_e
