Determine the internal quantum efficiency generated within a device when it has a radiative recombination lifetime of 80 ns and total carrier recombination lifetime of 40 ns. Correct Answer 80 %

The internal quantum efficiency of device is given by ηint = τ/τr = 40/80 ×100 = 80% Where τ = total carrier recombination lifetime τr = radiative recombination lifetime.
