Exercise 5.1.2-1

   
Take the equation for a forwardly biased (symmetric) pn-junction (neglect the generation term from the space charge region and the -  1 term) and then:
Calculate the areal density of injected carriers injected into the SCR for Si and GaAs from the current density for some relevant values of Ndop, L and t
Calculate the space density by using the matching values of the SCR width.
