Question

How does the width of a depletion region of a pn junction vary if doping
concentration is increased?​

Answer 1

Answer:Hence, the positive ions at n-side and the negative ions at p-side are increased over a given period. This increases the width of depletion region. Thus, the width of depletion region increases in the lightly doped semiconductors over a given period.

Explanation:If we increase, the doping the number if majority charge carriers (holes on p-side and electrons on the n-side) will increase as well. This would mean that the width of the depletion layer, which depends upon the charge carriers, would also increase.
