The doping concentrations in a silicon pn junction are Nd = 5 times 1015 cm-3 and Na = 5 times 1016 cm-3. The minority carrier concentration at either space charge edge is to be no larger than 10 percent of the respective majority carrier concentration. Determine the maximum forward-bias voltage that can be applied to the junction and still meet the required specifications. Is the n-region or p-region concentration the factor that limits the forward-bias voltage? Repeat part (a) if the doping concentrations are Nd = 3 times 1016 cm-3 and Na = 7 times 1015 cm-3.
