3.3.2 Gummel's Pentagon

The second example is a structure proposed by Gummel [28] as shown in Fig. 3.8b. It can be shown that the pentagon can be transformed into an equivalent quadratic resistor with side-length 2 ^. a. This is quite a severe test for both the grid generator and the implemented discretization of the semiconductor equations. The simulation results are identical to Fig. 3.11 and hence not shown.
