Ibach and Lüth, 7.1Solve the Schrödinger equation for the potential and calculate the charge density where the maximum k value is determined by the Fermi energy EF. Sketch ρ(x) and discuss the result (Friedel oscillations). Consider the cases of a typical metallic electron density of 1022 cm-3 and of a weakly doped semiconductor with a density of 1016 cm-3. |
