Options:
Answer:
C
Solution:
In an n-type semiconductor, pentavalent impurity atoms are added, which act as donors. These donor atoms introduce new energy levels known as donor energy levels.
The donor energy level is located in the forbidden energy gap (band gap), just below the bottom of the conduction band. The electrons donated by the impurity atoms occupy these energy levels and can easily be excited into the conduction band at room temperature.
Answer: the band gap and are close to conduction band.
