Consider the recombination process via bulk traps in a forward-biased pn homojunction diode. The maximum recombination rate is Umax. If the electron and the hole capture cross-sections are equal, which one of the following is FALSE?

Question

TuteeHUB · Accepted Answer

Umax depends exponentially on the applied bias.

TuteeHUB · Answer

With all other parameters unchanged, Umax decreases if the intrinsic carrier density is reduced.

TuteeHUB · Answer

Umax occurs at the edges of the depletion region in the device.

TuteeHUB · Answer

With all other parameters unchanged, Umax increases if the thermal velocity of the carriers increases.
