ECE 305 Homework #3 Due Monday, February 15 Note: in order to stay in sync with the other section, HW 3 and 4 has been modified with respect to that of the other section. Prob 1: Below are the energy bands as a function of position for a semiconductor (1μm = 1x10 -6 m). (2 pts) A. On the figure sketch and label an electron with 0.5 eV of kinetic energy and 0.5 eV of potential energy. (2 pts) B. On the figure sketch and label an electron with 1 eV of potential energy and 0.5 eV of kinetic energy (2 pts) C) On the figure sketch and label a hole with 0 eV of kinetic energy 0.5 eV of potential energy. E c E v Electron Energy (eV) 1.0 0.5 0 -0.5 Hole Energy (eV) 0 0.5 1.0 x(μm) 0 1 2 1.5
