$11.$ What effect does an increase in temperature have on the width of the depletion region in a PN junction? When the temperature of a PN junction increases, it affects the mobility and energy of charge carriers. What is the effect on the depletion region? A$)$ The width of the depletion region increases because of the increased number of minority carriers B$)$ The width of the depletion region decreases as the minority carrier concentration decreases C$)$ Temperature has no effect on the width of the depletion region D$)$ The depletion region becomes unstable at high temperatures
