A. higher than the energy at the bottom of the conduction band on the p side 

B. lower than the energy at the bottom of the conduction band on the p side 

C. lower than the energy at the top of the valence band on the n side 

D. lower than the energy at the top of the valence band on the p side 

E. the same as the energy at the bottom of the conduction band on the p side

Answer 1

B. lower than the energy at the bottom of the conduction band on the p side
