Question

What is the range of the carrier lifetime?

(a) Nanoseconds to microseconds

(b) Nanoseconds to hundreds of microseconds

(c) Nanoseconds to tens of microseconds

(d) Nanoseconds to milliseconds

The question was asked by my school teacher while I was bunking the class.

This question is from Carrier Life time in section Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

Correct option is (b) Nanoseconds to hundreds of microseconds

For explanation I would say: Carrier lifetime is defined as the existence of any carrier for τ seconds. Carrier lifetime ranges from nanoseconds to hundreds of microseconds.
