Consider putting down a metal electrode with a 4.50 eV work function on a piece of Ge which has an electron affinity of 4.00 eV, an intrinsic carrier concentration at 300K of 2.5 x 1013/cm3, and that is doped with 1.0 x 1016 donors/cm3. Assume an ideal contact. (a) What is the work function in the Ge? (b) Is this a Schottky barrier or an ohmic contact?
