Question 1 Answer
Draw the equilibrium energy band
diagram for this junction, including numerical
values for the Fermi level position relative
to the intrinsic level on each side.
Find the contact potential from the diagram.
Consider a silicon pn junction. The p side is uniformly
doped with 1016 acceptors/cm3. The n side is doped
with 1018 donors/cm3.
