4.2 Consider a silicon PN step junction diode with Nd 1016cm-3 and Na 5 x 1015cm3 Assume T 300 K. (a) Calculate the built-in potential Pbi (b) Calculate the depletion-layer width (Wdep) and its length on the N side (n) and P side p) Calculate the maximum electric field. Sketch the energy band diagram, electric potential, electric field distribution, and the space-charge profile. (c) (d) (e) Now let Na08cm3. Repeat (a). (b), and (c). Compare these to the previous results. How have the depletion widths changed?
