Band diagram for an n-type semiconductor

exercise 3_4964

A Si sample is doped with 10 17 As atoms/cm 3 . What is the equilibrium hole concentration p 0 at T = 300 K? Where is the Fermi level E F (i.e., the chemical potential m ) relative to the intrinsic Fermi level E i ( m i )? Draw a flat energy diagram showing the relevant energy levels.
