Question

2. The band diagram of a uniformly doped semiconductor is drawn below with V=0. (a) (10 pts) Sketch the band diagram with V>0. (6) (10 pts) Show with an arrow next to the electrons and holes, the directions of the electron velocities, Vn, and the hole velocities, Vp- (c) (10 pts) Show with an arrow, which way the electric field is pointing. (d) (10 pts) Show with arrows, which way the electrical current due to electrons, Jn, is flowing. (e) (10 pts) Show with arrows which way the electrical current due to holes, Jp, is flowing.
