is less than that at .
Text Solution
Verified by ExpertsThe correct answer is:
D
The field at the positive side of the depletion layer is higher, when there is no bias. One can say potential at 
side is lower than that at the 
side, because of the potential at the depletion sides. When there is no bias, anyway there will no current.
