Unformatted text preview: Sketch the banddiagram; be sure to include the Fermi levels. 2) In a certain piece of semiconductor, the electron concentration can be found according to the following formula: 10 1 cm 3 2m 1000 V where is the width of the piece. There is also a uniform electric field equal to cm pointing in the positive xdirection. The electron mobility is 1000 V.s cm 2 . Find the direction and magnitude of the electron drift current density, electron diffusion current density, and total current density at . (The system may or may not be in equilibrium)....
