Problem
There are two infinite slabs of charge, both of thickness d with the junction lying on the plane x=0. The slab lying in the range 0<x<d has a uniform charge density +ρ and the slab lying in the region −d<x<0 has uniform charge density −ρ. Find the Electric field everywhere and plot its variation along the x axis.
Note: This can be used to model the variation of electric field in the depletion layer of a p−n junction.
