Unformatted text preview: ECE 132 Quiz 6 Name __________________________ November 19, 2010 You have a p‐n junction doped equally on both sides so that n n0=pp0. Recall that the hole concentration and electron concentrations are both functions of position, p(x) and n(x), in the depletion region because of band bending Ψ(x). Show that at the metallurgical junction of the p‐type and n‐type materials (i.e. x=0) the electron and hole concentrations are equal, and the material is intrinsic – i.e. n(0)=p(0)=ni at x=0. Show all necessary steps, explain your work if it is not clear. ...
