1. Introduction to Surface Physics

But at the surface, we don't and there is a variation in electrostatic potential (, as a function of z. Draw an energy diagram, with ((-() < ((+(), with the Fermi energy Ef = (, the chemical potential for the electrons, and note that . Ef - ((-() = (bar, the Fermi level with respect to the bottom of the conduction band, and that the work function, ................
