Text Solution
Verified by ExpertsB
Statement I is correct but Statement II is incorrect.
Due to diffusion of holes from the 
-region to the 
-region and of electrons from the 
-region to the p-region and electric field is set up across the junction barrier. Once the depletion layer is formed, it is in equilibrium and becomes free of mobile charge carriers.
