Negative temperature coefficient. It means when temperature rises, the conductivity is decreasing. Thus, widening the depletion layer. So, when the temperature rises the depletion layer is widening.

If on increasing in temp built in potential decreases with -2.5mv/degcent.
Because the width of the depletion layer is proportional to sqrt (v) so width decreases.
Because the width of the depletion layer is proportional to sqrt (v) so width decreases.

With increase in temperature, applied voltage decreases at the rate of 2.5 mv/degcenti, then depletion width increases.
