The critical electric field for breakdown is approximately Ecrit = 3 x 105 V/cm. Determine the maximum breakdown voltage VB that the junction can sustain. Consult textbook for semiconductor parameters. Notice that this is NOT a one-sided n+p junction, so certain approximations are not valid! If not sure, use complete formula.
