Question

1. The Fermi energy of an n-type Si semiconductor is lower than that of a p-type Si semiconductor

 A. True
 B. False

Answer 1

It is false.

The Fermi energy of an n-type Si semiconductor is higher than that of p-type semiconductor. In an n-type Si semiconductor, the Fermi level of energy lies closer to the conduction band.

In a p-type Si semiconductor, the Fermi level of energy lies closer to the valence band.
