Abstract
We have observed the reflection recovery dynamics of photoexcited GaxI n1-xP/InP:Fe (x<0.18), using the pump-probe technique, and found that the delay time of the reflection recovery dynamics increases with incr easing gallium composition. To understand the experimental results, we have also performed a simulation study, which is in good agreement wi th the measured data, and shows that ambipolar diffusion plays a domin ant role in determining the photoexcited carrier dynamics.
