Explanation: The rise in temperature excites the charges, which go & recombine with the charges in the depletion region decreasing its width. Higher the temperature, lesser is the E.M.F required to turn on the device. 9. In the equilibrium state, the barrier potential across a unbiased silicon diode is ___
A. 0.3 V
B. 0.7 V
C. 1.3 V
D. 0 V
Answer:A
Explanation: The rise in temperature excites the charges, which go & recombine with the charges in the depletion region decreasing its width. Higher the temperature, lesser is the E.M.F required to turn on the device. 9. In the equilibrium state, the barrier potential across a unbiased silicon diode is ___
A. 0.3 V B. 0.7 V C. 1.3 V D. 0 V
Explanation: Barrier potential is due to the charges that establish an electric field across the two junctions.
