Question

In which direction is the electric field established by the fixed ions?

Options

• From the p-side to the n-side

• From the n-side to the p-side

• From the depletion region to the n-side only

• From the depletion region to the p-side only

Answer 1

Fixed ions establish an electric field from the n-side to the p-side. This field produces the barrier potential across the depletion layer.
