In a p-n junction with open ends,

Options

A. there is no net charge transfer between the two sides
B. there is a constant electric field near the junction
C. the holes and conduction electrons systematically go from the p-side to n-side and from n-side to p-side respectively
D. there is no systematic motion of charge carriers.

Answer

A, B, D

Explanation

In a p-n junction with open ends, the net cgarge transferred between the two sides is zero. A depletion between the two sides is zero. A depletion layer is created at the junction due to diffusing of majority carriers from one side to another and a constant electric field is set up across the junction.
