As we increase the temperature the gap b/w the pn junction decreases so there should be breakage/decrease of barrier potential.

In forward bias barrier potential is decrease if temp increase, because barrier potential is the value of depletion width.

In fb region characteristics of diode shifts towards left by rise in temp therefore the barrier potential decreases.

In fb if tempr is increased the distance b/w vb & cb is decreased due to thermal conductivity.

When diode reverse bias act as open circuit and no free of the electron. So no current in diode.
