Question

Why depletion layer shrinks when applied voltage increased?

Answer 1

When you form a PN junction you get diffusion of charge carriers from one side into the other. ... Electric field is the integral of charge density. This reduction in depletion width thickness causes an increase in electric field because the charge density has increased and the depletion width has decreased.

Answer 2

hy
here is your answer
 If the depletion region width shrinks as temperature increases its because the density of carriers is increasing. The applied voltage determines
