-
At the junction of a pn-diode—
-
- The depletion region has an electrostatic potential which makes p-side positive with respect to the n-side
- The space charge region exists predominantly in the heavily doped junction
- Holes are prevented from diffusing from n-side to the p-side
- The electric field at the junction is of such value as to cause the diffusive tendency to be counterbalanced by the drift velocity of electrons and holes
Correct Option: D
NA
