GATE ECE 2020 EC Q7: Electronic Devices

Consider the recombination process via bulk traps in a forward biased

homojunction diode. The maximum recombination rate is

. If the electron and the hole capture cross-sections are equal, which one of the following is FALSE?

Your answerChoose one option.

With all other parameters unchanged,

decreases if the intrinsic carrier density is reduced.

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

depends exponentially on the applied bias.

With all other parameters unchanged,

increases if the thermal velocity of the carriers increases.
