In semiconductors at room temperature,

Options

  1. Athe valence band is completely filled and the conduction band partially filled.
  2. Bthe valence band is completely filled.
  3. Cthe conduction band is completely filled.
  4. Dthe valence band is partially empty and the conduction band partially filled.

Correct answer

D. the valence band is partially empty and the conduction band partially filled.

Step-by-step solution

In semiconductors at room temperature the electrons get enough energy so that they are able to over come the forbidden gap. Thus at room temperature the valence band is partially empty and conduction band is partially filled.
