In semiconductors at room temperature,

Options

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

Correct answer

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

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.
