The generation currents are not substantialy affected by externally applied electric fields. Why not?
  • There is already an electric field in the junction zone.
  • An external field would inhibit the formation of hole-conduction electron pairs and thereby cancel the increased potential difference.
  • The numbers of conduction holes and electrons generated are small and independent of external fields.
  • Externally applied fields don't affect tho motion of holes and electrons within the junction zone.

Answer #1

The numbers of conduction holes and electrons generated are small and independant of external fields

The generation currents are not strongly altered by externally applied electric fields. However, applied electric fields can affect the drift current. If the applied field increases the potential of the p-type material, then holes are pushed away toward the n-type side more readily, and electrons are drawn away from the n-type side more readily
