Options:
Answer:
C
Solution:
In an n-type semiconductor, pentavalent impurity atoms are added, which donate extra electrons.
These donated electrons occupy discrete energy levels known as donor energy levels.
The donor energy levels are located in the forbidden energy gap (band gap) just below the bottom of the conduction band (typically eV to eV below it).
Because they are very close to the conduction band, these electrons can easily be excited into the conduction band at room temperature.
Answer: the band gap and are close to conduction band.
