A small percentage of impurity is added to an intrinsic semiconductor at 300 K. Which one of the following statements is true for the energy band diagram shown in the following figure?

A small percentage of impurity is added to an intrinsic semiconductor at 300 K. Which one of the following statements is true for the energy band diagram shown in the following figure? Correct Answer Intrinsic semiconductor doped with pentavalent atoms to form an n-type semiconductor 

The new energy level is close to the edge of the conduction band (Ec).

Thus it is an n-type semiconductor that is formed by doping a pure or intrinsic semiconductor with a pentavalent atom.

Note:

Fermi level of an intrinsic semiconductor is as shown:
